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?

Whew! It’s a hot one! And whenever the temperature soars, you need to stay hydrated, especially when you’re outside or exercising. But all cold drinks aren’t equal when it comes to healthy hydration. Which beverages shouldn’t have a prime spot in your cooler when you’re wearing braces or aligners?

• Soft Drinks

You’re probably not surprised to find soft drinks at the top of the list. After all, sugar is a) a big part of what makes soda so popular, and b) not a healthy choice for your teeth.

Sugar is a favorite food source for the oral bacteria that make up plaque. These bacteria convert sugar into acids, and these acids attack the surface of your tooth enamel. Over time, the minerals which keep enamel strong begin to erode, and weakened, eroded enamel is a lot more susceptible to cavities.

So, what about sugar-free drinks? Does this make soft drinks a better choice? Unfortunately, you can take the sugar out of many sodas, but you can’t take the acids out. Most soft drinks are very acidic, even without sugar, and will cause enamel erosion just like the acids created by bacteria will.

• Fruit Drinks

Fruit juice provides us with vitamins, which is great, but it’s also full of natural sugars and acids. And blended fruit drinks and fruit punches often contain added sugars and added citric acids. Best to choose 100% fruit content and check the labels before you buy. (And you can always get refreshing fruit flavor by adding a slice of fruit to a glass of water.)

• Sports Drinks

You might be surprised to see these on the list—after all, they promise healthy hydration while you’re working out. And hydration is healthy—but sugars and acids aren’t. Even when the label tells you there’s no added sugar, that same label will often reveal high amounts of citric acid. In fact, some sports drinks are more acidic than sodas.

We’ll make an exception, though, for thirsty people who participate in sports or activities that require a lot of physical exercise and produce a lot of sweat. When we sweat, we lose electrolytes, those ionized minerals which help regulate many vital bodily functions. Talk to Dr. Kathleen Tavarez about which sports drinks are best for you if you need to replenish your electrolytes when working out.

So, what’s your best hydration choice on a hot day? Water! It not only hydrates you, it cleans your teeth, it helps you produce saliva, and it often contains tooth-strengthening fluoride. But if you only have sports drinks in the cooler, or if you just want to enjoy a soft drink or a bottle of juice from time to time, no need to go thirsty. We have some ways to make sure your teeth are safer, even with this tricky trio:

• Rinse with water after you drink a sugary or acidic drink. And remember to brush when you get home.
• Be choosy. Check labels for added sugars and acids.
• Don’t sip your drinks all day long. Saliva actually helps neutralize acids in the mouth, but sipping acidic beverages throughout the day doesn’t give saliva a chance to work.
• Use a straw to avoid washing your enamel in sugars and acids.

While sugar and acids are never good for your teeth, it’s especially important to reduce your exposure while you’re in braces or aligners.

• Increased sugar means increased plaque and bacteria, which can collect around your brackets. When plaque isn’t cleaned away, bacterial acids cause mineral erosion, which shows up as white spots on your enamel. You don’t want to see a collection of white spots when those brackets come off!
• Filling a cavity might require the (temporary) removal of part of your braces.
• There’s a reason Dr. Kathleen Tavarez and our team recommend that you only drink water with your aligners on. If you wear them while you drink sugary and acidic beverages, the liquid collects in your aligner tray, literally bathing your teeth in sugar and acid—and speeding up the process of erosion and decay.

You need to keep hydrated when it’s hot. When you’re packing your cooler, choose drinks that are healthy for your entire body, including your teeth and gums. Ask our Menlo Park or San Carlos, CA team for the best choices in cold drinks to make sure you’re getting the hydration you need—without the sugar and acids you don’t!

Modern dentistry has made the most of today’s technological innovations. And we’ve come a long way from the fraying sticks our ancestors used as toothbrushes.

On the other hand, while it’s a lot better than a fraying stick, the manual toothbrush model you’ve used for years might be ready for an upgrade. Should you take this opportunity to try out some new technology offering all the bells and whistles? Let’s answer that question by asking a few more questions.

Happy with your manual brush?

If you like your manual toothbrush and it’s doing the job, by all means, stick with it. But even your old familiar brush can evolve:

• There are lots of bristle options, but soft bristles are almost always the way to go. Medium and hard bristles can be too abrasive for your enamel.
• Heads come in a variety of sizes, so make sure the head size is comfortable. You want to be able to maneuver to reach every tooth surface, which a too-large brush head just can’t do.
• Try a different handle shape if you’re having trouble maneuvering and keeping a firm grip.
• Change your brush regularly. Brushes are effective for about three months before the bristles start to fray and breakdown. This is a good opportunity to experiment with different brands and styles.

Does your old brush suit your current needs?

Different types of manual toothbrushes are available for effective and comfortable brushing when you need options that a typical brush doesn’t provide:

• Special orthodontic toothbrushes are designed with bristles trimmed to fit around brackets and wires and smaller heads to reach into tight places.
• For those with mobility issues, brushes with larger or easy-grip handles make cleaning more comfortable.
• Brushes with extra-soft bristles are available if you have enamel erosion or sensitive gums.
• Because many women find their gums become especially sensitive during pregnancy, there are brushes designed especially for moms-to-be.

Is it time to go electric?

If you haven’t tried an electric toothbrush before, you might find that getting braces is a great reason to give one a spin.

• Electric toothbrushes can outperform manual models. A dedicated brusher might manage hundreds of brushstrokes for each minute of brushing, while an electric brush can provide thousands. If, despite your regular brushing, you have plaque build-up, an electric brush might be a good alternative to your manual brush.
• Models are available which can alert you when you’re brushing too hard—which is important for your enamel if you’re a heavy-handed brusher.
• If you tend to *think* you’ve brushed for the recommended two minutes, but have *actually* brushed 32 seconds, some electric brushes come with timers!
• There are tapered electric orthodontic brush heads designed just for people with braces.
• Electric brushes have bigger handles and can be easier to grip.

Is your current brush doing the job?

So, should you stick with the familiar toothbrush that’s worked for you all these years, or take this opportunity to try out some new technology that offers all the bells and whistles? The answer is clear: the right brush for you is the one that works!

If your regular checkups show that plaque is under control, you’re doing just fine with the brush in hand. If you or Dr. Kathleen Tavarez notice plaque buildup, it’s time to consider making some changes. Whether it’s a question of tools, techniques, or time spent brushing, your Menlo Park or San Carlos, CA dental team has the answers you need for state-of-the-art dental hygiene.

Now that you’re in orthodontic treatment, you’re probably spending more time taking care of your teeth than ever before. So, why did your dentist find a cavity at your last checkup? Let’s look at some of the potential culprits.

• Brushing More Doesn’t Always Mean Brushing Well

Even for adults with decades of experience, proper brushing technique is often overlooked. Brushing’s not as effective without covering all the tooth surfaces (inside, outside, and molar tops), holding the brush at a 45-degree angle, gently brushing the teeth with small strokes, brushing for at least two minutes, and flossing between the teeth at least once a day.

If you wear braces, you must also take care to reach all the spots between and around your wires and brackets. Which leads us to . . .

• Are You Using the Right Tools?

Even with perfect brushing form, your braces will be a challenge for a regular toothbrush and floss. The right tools make any job easier, and that includes cleaning your teeth while you’re wearing braces.

Specially designed brushes with bristles designed to work with your brackets, floss made to fit behind wires, tiny cone-shaped interproximal brushes that fit between your teeth and around your brackets—all these tools are made specifically to remove plaque and food particles from your teeth and your braces.

• Crunchy, Hard, and Sugary Aren’t the Only Problem Foods

You know sugary foods should be limited because sugars are the favorite food of cavity-causing bacteria. And hard and crunchy foods are off limits altogether because they can damage your braces. But what about treats which look soft and harmless? Well, looks can be deceiving!

Starches in soft, carb-rich foods like potato chips and white bread quickly break down into sugars. What’s more, they tend to stick around brackets and in between the teeth, giving those cavity-creating bacteria plenty of nourishment.

This isn’t to say that you must eliminate all sugars and carbs from your diet. But when you wear braces, be especially mindful about brushing or at least rinsing thoroughly whenever you have a snack.

• Biology

Some people are biologically more prone to cavities, even with attentive brushing and flossing, so you shouldn’t feel guilty if you don’t have a perfect checkup every time. Instead, be proactive. Ask Dr. Kathleen Tavarez for brushing and cleaning advice the next time you visit our Menlo Park or San Carlos, CA office—and then follow it!

It’s not just spending more time taking care of your teeth—it’s using your valuable time the best way possible. It’s always time well-spent brushing properly, eating mindfully, and working with your orthodontist and your dentist to create a beautiful, healthy, cavity-free smile.
