Talking Over Your Underbite

September 24th, 2025

You’ve been told that you have a malocclusion called an “underbite.” Let’s look at just what this diagnosis means, and what it means for you.

Just what is an “underbite”?

A malocclusion is another way of saying that you have a problem with your bite, which is the way your jaws and teeth fit together when you bite down. In a typical bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth.

An underbite, on the other hand, results when the lower teeth and jaw extend further forward than the upper teeth and jaw, causing the bottom teeth to overlap the top teeth.

What causes an underbite?

Underbites tend to be genetic, and run in families, so, most often, an underbite is something you’re born with. The size of your jaws, the shape of your teeth, or both will affect your bite.

A smaller number of underbites develop because of injuries or early oral habits, such as prolonged and vigorous thumb sucking or tongue thrusting.

How do we treat an underbite?

Your treatment will depend on the type and severity of your underbite, and your age when treatment occurs.

  • Braces and Aligners

If your underbite is a slight one, caused, for example, by crowded or overly large teeth, braces or clear aligners can help move the teeth into proper alignment.

  • Functional Appliances

If the underbite is caused by a problem with upper and lower jaw development, devices called functional appliances can be used to help guide the growth of the jawbones while a child’s bones are still growing and forming.

If you’re a young patient, two appliances commonly used to help correct an underbite are palatal expanders, which gradually widen the upper jaw if it’s too narrow, and reverse pull headgear, which fits both inside the mouth and outside on the face, and provides a steady, gentle pull to encourage the forward growth of the upper jaw.

  • Surgical treatment

In some severe cases, surgical treatment can correct an underbite by reshaping the jawbone itself and positioning it further back to align properly with the upper jaw.

Why treat your underbite?

A serious underbite can cause damaged teeth and enamel, painful problems with the temporomandibular joint, headaches and facial pain, sleep apnea, difficulty chewing, eating, and speaking, and can affect confidence and self-esteem.

By following your treatment plan, you’ll not only prevent these consequences, but you’ll achieve major benefits—a healthy, comfortable bite, and an attractive, confident smile. Want to know more? Talk it over with Dr. Razavi at our Kanata, Ontario office for all the information you’ll need!

Worst Candy for Braces

September 17th, 2025

Most kids love candy; actually, most people in general love candy. So when it comes time for you to get braces there can often be a natural conflict between candy consumption and maintaining the integrity of your braces. For that reason, Dr. Razavi and our team know that it’s good to know which types of candy are not good for your braces. To better illustrate, here are some candies that you will want to avoid.

Caramel

Caramel is a sweet and often exceedingly sticky and chewy type of candy that just does not mix well with braces. Caramel can cause a mess in regular teeth, but teeth with braces are a whole other story. The sticky candy can very easily get lodged and stuck between the teeth, gums, and braces, making for a difficult task of cleaning your mouth. And if your teeth don't get cleaned properly, cavities can easily form. If you get cavities while you have braces, that could mean additional appointments at our Kanata, Ontario office and an extended treatment time.

Salt Water Taffy

Another sticky and chewy candy to avoid with braces is salt water taffy. For many of the same reasons as caramel, it is best to avoid taffy until you get your braces removed. It may be a long wait, but when it comes to the health of your teeth, and the purpose of your braces, it really is best to avoid taffy.

Popcorn

Popcorn of any kind is best to avoid when you have braces. The kernels can easily do damage to the braces as you chomp on them, and they can get stuck between your teeth and the braces causing discomfort and further complications. In this sense it does not matter which flavor of candy popcorn you eat, all popcorn is bad news until you get your braces off.

Generally speaking, any candy that is chewy, crunchy, or sticky is not a good idea to eat with braces in your mouth. These types of candy will make life wearing braces much more difficult than if you were to just wait until your braces come off. With a little patience you will be back to eating all your favorite candy again, and with straightened teeth at that.

Treatment Options for TMD

September 10th, 2025

Temporomandibular dysfunction (TMD) refers to a diverse range of disorders that relate to muscular function in the jaw and face — the temporomandibular joint (TMJ). That could mean difficulty opening your mouth, pain in the jaw or face, or any sort of problem with the jaw joint.

TMD can be difficult to diagnose because of the varied causes. Whatever the case, an accurate diagnosis from Dr. Razavi helps make treatment as successful as possible.

Most often, jaw problems will resolve themselves within several weeks or months. Surgeries like arthrocentesis, arthroscopy, and open-joint surgery should be a last resort. More conservative and reversible treatments should come first and are in fact the most critical step in the treatment of TMD.

Less invasive treatments like acupuncture and splints can be helpful, but that will depend on your particular case. It’s worth your while to speak with Dr. Razavi at our Kanata, Ontario office to learn about solutions that could work for you.

A combination of treatments will most often produce the greatest relief for TMJ patients. It’s a good idea to avoid activities that overuse the jaws, such as chewing gum or clenching your jaws.

You can be proactive in finding relief for TMD by trying the following remedies at home:

  • Eat soft food: When you eat soft and/or blended food, your jaw gets an opportunity to rest. Avoid chewy and crunchy food, and food that requires you to open your mouth wide, like apples or corn on the cob.
  • Apply moist heat: A hot water bottle wrapped in a moist towel can help reduce symptoms.
  • Apply ice: Applying an ice pack wrapped in a cloth or towel for no longer than 15 minutes may also reduce pain and promote healing.
  • Do jaw exercises: A physical therapist can help identify the exercises that will work for you. Jaw exercises have been shown to be an effective treatment method that can be performed at home.
  • Relaxation: Actively try to relax the muscles of the face and lips, and let your teeth come apart. Many find meditation, yoga, and slow, deep breathing to be helpful for reducing stress and tension.
  • Avoid wide yawns: Keep your fist under your jaw when you feel a yawn coming on, to keep your jaw from opening too widely.

Foods can Wreak Havoc on Your Enamel

September 3rd, 2025

It’s possible to develop tooth decay even when you take great care of your teeth. Brushing and flossing may not be enough to keep your teeth healthy, depending on your diet. Cavities, discoloration, and decay are still possible when certain foods feature in your daily intake. Keep an eye out for foods that will damage your enamel and cause the very issues you’ve been trying to avoid.

What causes enamel damage?

Tooth enamel is the hard outer layer of your teeth that is made of various minerals. Tooth decay results when the acids in your food react with the minerals in your enamel. Strongly pigmented foods may also cause unsightly discoloration on the surface of your teeth. Avoid wreaking havoc on your beautiful smile by identifying the foods that can harm your enamel.

Acid

Acidic food is your teeth’s worst nightmare! This is the greatest cause of enamel damage, even if you brush and floss regularly. To avoid damaging your teeth, make sure you can determine whether a food is acidic or not.

The pH levels are a way to determine acidity on a one-to-seven scale. This defines the relative acidity or alkalinity of a food or substance. Foods with high pH levels are not as likely to harm your enamel.

It’s wise to avoid or minimize foods that are high in acids. Highly acidic food can include fruits such as lemons, grapefruit, strawberries, grapes, and apples. Moderately acid foods may surprise you; they include tomatoes, maple syrup, pickles, and honey.

Not surprisingly, eggs and dairy products such as milk and cheese contain the least amount of acid. Red wine and coffee can also discolor your enamel if they’re drunk in excessive amounts.

What can I do to prevent enamel damage?

There are plenty of ways to avoid discoloration and decay of your enamel. The best thing to do is limit the amount of high-acid foods, including sugary juices and soda, in your diet.

Another way is to brush and floss regularly, an hour after each meal. If you can’t make time to brush, an easy solution is to swish your mouth with water or mouthwash to rinse away any leftover acidic particles.

Damaged tooth enamel may be common, but is avoidable when you know which foods to stay away from and the steps to take after you do eat highly acidic foods. Take our advice and you’ll be sure to slow down any future discoloration and decay that happens in your mouth.
