What Is A Sports Guard And Do You Need One?

Sports guards are a form of mouthguard that is used during contact sports such as hockey, lacrosse and basketball. Any time there is a chance of trauma from an object or another person, a sports guard is recommended. There are two main types of sports guards, which are professionally made and store-bought. Both types have their pros and cons. 

Professionally Made Sports Guards 

Professionally made sports guards are the gold standard for sports guards because they fit precisely to your mouth and teeth and offer you the best protection. This type of sports guard is made by taking an impression of your teeth and sending the impression to a dental lab to be made. The sportsguard will be fabricated out of acrylic. Because professionally made sports guards offer the best protection and are custom made, they are more expensive than store-bought mouth guards. Sometimes the cost of the sports guard may be covered by your insurance provider. 

Store Bought Sports Guards 

Store-bought sports guards are only recommended in a couple of situations because they don’t do as good of a job preventing injury and trauma. Store-bought guards will be recommended for children whose mouths and teeth are constantly changing, as well as for someone going through orthodontic work, for the same reason. Store-bought guards are usually boil and bite, which means they need to be heated up and moulded to your teeth.

How to Care for Your Sports Guard 

  • Make sure to clean your sports guard between use with a separate toothbrush and store it in a sports guard case
  • Never use hot water on your sports guard as this may change the shape 
  • Never remove your sports guard with your tongue or chew on it 
  • If your sports guard is loose or has cracks and chips in it, bring it into your dentist to take a look at it, it may be time for a new guard 

If you believe you may benefit from a sports guard, or have any questions about sports guards, contact us today to schedule an appointment.

Why Does Your Dentist Need Dental X-Rays?

Dental x-rays are pictures that are taken of our teeth that show the underlying structures beneath the soft tissues, and in areas, we can’t visually see. X-rays are black and white images that show us the density of oral structures. On an x-ray, the lighter a structure is, the denser it is (called opaque), the darker a structure is, the less dense it is (called radiolucent.) Therefore enamel of teeth shows up very light, and gum tissue shows up very dark, almost not noticeable on an x-ray. 

Why Are X-Rays Taken?

  • Checking for cavities on biting surfaces, in-between the teeth and underneath the gums 
  • Checking for infections at the root (apex) of any of the teeth 
  • Monitoring the health and levels of the bone and periodontal ligament support
  • Checking the angulation of tooth roots 
  • Checking for any abnormalities such as cysts 
  • Monitoring the health of past restorative work 
  • Checking wisdom teeth impaction
  • Monitoring the health of the jaw joint 
  • Used for patients with dental braces (before and after)
  • In kids, checking the eruption of baby teeth 
  • In kids, checking for extra or missing adult teeth under the gums

When Are X-rays Recommended? 

X-rays are recommended based on an individual’s need. If there is an issue or concern, an x-ray will be needed to get a full picture of what is going on. Cavity check-up x-rays are recommended every 1-3 years based on cavity risk. Someone who has never had a cavity will be recommended less frequently, and someone who is cavity prone will be recommended more often. 

Dental Considerations

X-rays are only taken when needed/ recommended. Most dental offices offer digital x-rays, which significantly reduce the radiation exposure. Lead aprons are used to cover the vital structures in the neck and torso. Regular check-up x-rays (a series of 4 x-rays) are around the same amount of radiation as the average background radiation in 1 day or the radiation from a 1-hour flight (very minimal!)

If you have any questions about dental x-rays, we encourage you to contact us today to schedule an appointment.

What is Involved in a Complete Oral Exam?

The difference between a complete oral exam and a regular check-up exam is the detail of the diagnosis during the exam. During a complete oral exam, time will be taken to review and check every facet covering overall medical health, gum and teeth health. A comprehensive oral exam is recommended every 3-5 years or at the first visit to a new dental office. It gives a complete break down of the health of your teeth, gums and mouth. Comprehensive oral exams may be recommended more frequently if there are concerns.

What to Expect During a Complete Oral Exam 

  • Complete or updated medical history. Often your overall health affects your oral health and visa versa. 
  • Addressing your chief concerns regarding any cosmetic or functional problems 
  • Extraoral exam checking the tissues of your face, lips and neck 
  • Checking the health of your lymph nodes and looking for any lumps or bumps in the neck 
  • Checking your TMJ which is the jaw joint for any pain, clicking or deviation 
  • Intra Oral exam to check the tissues of your cheeks, tongue, the roof of your mouth, floor of your mouth and throat 
  • Oral cancer screening, checking for any abnormalities 
  • Checking for any signs of clenching or grinding 
  • Completing or updating the odontogram and recording any missing teeth, current fillings, dental crowns, implants, bridges, etc. 
  • Checking for any cavities, chips, wear, fractures, infections, etc. 
  • Taking any x-rays that are recommended to check the health of your teeth and bone 
  • Pictures may be taken of your teeth and mouth to assess for changes over time 
  • Completing a periodontal exam which is an exam of the health of the gums and the best indicator of gum disease 
  • Reviewing brushing and flossing habits 
  • Creating a customized treatment plan based on your needs 
  • Making any necessary referrals such as to an oral surgeon, orthodontist or periodontist 

If you have any questions about complete oral exams or believe you may be due for a complete oral exam, we encourage you to contact us today to schedule an appointment.

Learn About Different Brushing and Flossing Techniques

Of course, you know that it is essential to brush your teeth at least twice a day and to floss at least once a day, but did you know that the technique you use to brush and floss your teeth has severe effects on the health and longevity of your teeth? It is vital to use the correct methods for optimal plaque removal to keep your teeth and gums as healthy as possible. Listed below are several different brushing and flossing techniques. Make sure to discuss with your dentist or dental hygienist which method will work best for you. 

Circular Brushing Method

Angle your toothbrush toward your teeth and gums and use a circular motion for 2-3 teeth at once. This is the easiest brushing technique and is usually recommended for children.

Bass Brushing Technique

Hold the bristles of your toothbrush at a 45-degree angle toward your teeth, allowing the bristles to slip slightly underneath your gums and use a vibrating back and forth stroke, accessing 2-3 teeth at a time. Make sure to spend an adequate amount of time in each spot before moving on to the next.

Modified Bass Brushing Technique

Using the same technique as bass, but using a rolling motion away from the gums after each set of teeth (a rolling stroke upward for the bottom teeth and downward for the upper teeth).

Rolling Stroke Brushing Method

In this method, you will use a rolling technique with your toothbrush away from the gums. Angle the bristles toward the gum line and roll the toothbrush away from the gums.

Electric Toothbrush Technique

To use an electric toothbrush, make sure to let the toothbrush do the work for you. Electric toothbrushes use their unique type of toothbrush technique (usually an oscillating or sweeping motion), so you simply have to access the teeth and gum line and slowly bring the toothbrush across, accessing every tooth.

“C” Flossing Method

This is the best technique to use with manual dental floss. It involves accessing the space between teeth with the floss and then hugging the floss slightly around each tooth to remove as much plaque as possible. After guiding the floss through the space between teeth, first, hug the front tooth, go over the gums but not out of the contact, and hug the floss around the back tooth, then move on to the next area.

Floss Wands

With floss wands, you are unable to use c-method flossing, so make sure to access the contact by guiding the floss through, and make sure to access underneath the gum line with the floss.

Water Flosser

A water flosser uses a jet of water to flush out bacteria. It may take some practice to get into the groove. Find the right angle to spray the jet of water between each tooth. 

If you have any questions about brushing or flossing techniques, or about what technique or tool will work best for you, we urge you to contact us today to schedule an appointment.

Pros and Cons of Removable and Fixed Retainers

Retainers are used to hold teeth in a certain place, often after orthodontic work is completed. After orthodontics, if no retainer is used, the teeth may shift and revert to the position they started in. Your dentist or orthodontist will recommend either a removable or a fixed retainer to keep your smile looking aligned. 

Removable Retainer 

With this type of retainer, you can put in and take out when needed. It is recommended to wear your retainer as much as possible. The exception being when eating and brushing or flossing. Sometimes they are only recommended for night-time use. Make sure you discuss with your dentist or orthodontist about the recommended usage. Removable retainers will either be a clear tray or have a wire front depending on what the use. 

Advantages of Removable Retainers

The advantage of a removable retainer is that you can take it out and put it back in. This means that it is much easier to brush and floss your teeth, and you can take it out of your mouth when needed.

Cons of Removable Retainers

For the retainer to work, you have to wear it. If a patient isn’t compliant with wearing their retainer for the recommended amount of time, their teeth may be more susceptible to shifting with time. If you don’t wear your retainer consistently, sometimes it can feel tight or sore when putting it back in. 

Fixed Retainer

A fixed retainer is a wire that is glued to the back of your front teeth (either bottom, top or both) to hold your teeth in place and prevent shifting. Fixed retainers stay in place without having to be taken out and put back in.

Advantages of Fixed Retainers

The benefit of a fixed retainer is permanent retention. Because the fixed retainer can stay in for eating, brushing and flossing, it is continually holding the teeth in the correct position.

Cons of Fixed Retainers

Because the fixed retainer cannot be removed, it cannot be taken out for brushing and flossing. The wire causes difficulties with cleaning as there are more areas where plaque and bacteria can build up. There is more work involved in keeping your teeth clean when you have fixed retainers. Floss threaders, super-floss and even a water flosser, are important tools to use to help you clean your teeth clean.

If you believe you would benefit from either a fixed or removable retainer, or have any questions about them, we encourage you to contact us today to schedule an appointment. 

Can Sparking Water Harm your Teeth?

We all know that sugar intake affects our teeth and can lead to tooth decay, but did you know that the PH level can also change the risk to teeth? The PH level is how acidic or basic something is that we are eating or drinking. Sparkling water is thought to be more acidic than flat water because of the added carbonation. 

The Study 

Extracted teeth that were donated were used for the study, which tested the effect of sparkling water vs. flat water. Teeth were submerged for some time in both types of water, and the result? Sparking water appeared to have no adverse effect on the teeth, much like flat water.  

It appears that sipping on sparkling water throughout the day will not lead to cavities or enamel erosion. But be aware, any sparking water with additives like citrus may have a more damaging effect on the teeth as the acidity level will be higher. Also, the best way to have your sparkling water would be in a machine where you can make it at home, because the use of tap water will incorporate fluoride into the sparkling water, giving you that added anti-cavity protection.

What Not to Drink 

Any drinks containing sugar or high acidity levels are not going to be good for your teeth. This means soda, fruit juices with added sugar and even natural juice with natural sugar all have a cavity-causing effect on the teeth.  

Frequency Vs. Quantity 

Think about it this way; the frequency in which you consume sugary or acidic drinks is the most crucial factor in cavity risk. If you have a small glass of orange juice, but you sip it slowly over the course of a few hours, the exposure to sugars will actually be greater than gulping back a sugary soda all at once (although not good for your health!). The exposure time is an important factor in cavity risk.   

If you think you may have acid erosion or a cavity, or have any questions about cavity-causing foods or drinks, we encourage you to contact us today to schedule an appointment.

How To Deal With Sensitive Teeth

Sensitive teeth can be a daily nuisance, and sometimes it’s not clear what is causing the sensitivity. It is essential to find the root cause of the sensitivity and eliminate it. Thankfully, there are several options for reducing symptoms of sensitive teeth.  

Sensitivity Toothpaste

Sensitivity toothpaste helps to reduce the symptoms of sensitivity by applying a thin protective layer on the teeth. This protective layer helps block microscopic tubules that lead from the outer part to the inner part of the teeth. Sensitivity toothpaste can provide instantaneous and long-lasting sensitivity relief. 

sensitivity toothpaste mississauga dentist


A desensitizer acts in a similar way to sensitivity toothpaste by blocking microscopic tubules to prevent sensitivity. When you consume anything that may cause sensitivity, the sensation cannot enter the underlying tooth structure to cause sensitivity. Desensitizer has to be applied in office by a dental professional and usually lasts several months. 

Reducing Sweets/Acids in Your Diet 

A great way to prevent sensitivity is to consume fewer sweets and acids in your diet. These types of foods can lead to cavities and erosion on your teeth, creating sensitivity. 

Use a Soft/ Electric Toothbrush

Sensitivity can be caused by aggressive brushing, or by use of a toothbrush that is too hard on your teeth and gums. Aggressive brushing and hard toothbrushes can lead to recession of the gums and abrasion of the teeth. Try using an electric toothbrush with a pressure indicator or an extra soft or soft toothbrush.  

Dental Fillings

Dental fillings can be used to fill in areas of recession and wear to prevent sensitivity. If sensitivity is caused by gum recession, a thin layer of filling material can be placed to protect from external stimuli. Sensitivity due to wear can be treated with dental filling material.

If you are suffering from sensitive teeth, or have any questions about sensitive teeth, we encourage you to contact us today to schedule an appointment. 

What Is Invisalign and How Could it Benefit You?

Invisalign is a form of orthodontic treatment that involves a series of clear plastic aligners that slowly straighten your teeth and improves your bite. Invisalign works by using aligner trays to move your teeth slowly and effectively. The aligner trays are secured to teeth through the use of attachments that are bonded to the teeth. Attachments are small pieces of plastic resin that get bonded on the front surface of several of your teeth. But don’t worry; the attachments are tooth coloured and difficult to see. The length of treatment and the cost of the Invisalign will depend significantly on the work to be done. Your specific treatment plan will be discussed with you before treatment. As well, you will be able to ask any questions you have.

 How is Invisalign Made?

Before you start your treatment, you will see your dentist or orthodontist to have impressions taken of your teeth. These impressions will be sent to the Invisalign lab, which will then create a detailed, custom, digital treatment plan and a series of Invisalign aligner trays. The number of trays in your treatment plan is based on how much work and movement is needed. You will see your Invisalign trained dentist or orthodontist every 4-6 weeks to assess results and to get more trays. You will be instructed on how frequently to change your trays. Usually, it is every 1-2 weeks.

 Important Invisalign Facts

  • It is essential to maintain excellent oral hygiene during your Invisalign treatment. Make sure to brush at least twice and day and floss at least once a day. The most beneficial practice is to always brush after eating and before putting your trays back in. 
  • Use a fluoride toothpaste and mouthwash to prevent cavities during your Invisalign treatment. 
  • Wear your trays at least 20-22 hours a day, try only to take them out when eating, drinking and cleaning your teeth. 
  • Clean your Invisalign trays with a separate toothbrush and warm water. Never use hot water on your Invisalign trays as it could warp them. 
  • Invisalign is an excellent option for most cases, including if you’ve already had braces before and notice some shifting. 
  • Aligners are made of a select type of thermoplastic material explicitly created for Invisalign.

It is essential to discuss with your dentist or orthodontist what outcome you hope to achieve before starting Invisalign treatment. Outcomes, length of treatment, cost, etc. will all be discussed before beginning treatment. If you have any questions about Invisalign, we encourage you to contact us to schedule an appointment today.
