Five Clues That It’s Time to Replace Your Toothbrush

February 5th, 2025

Your dashboard lights up when your car needs an oil change. Your family smoke detector beeps when you need to switch out the batteries. But when it’s time to replace your toothbrush, you’re on your own. Luckily, there are several not-too-subtle clues that you should be shopping for a new model.

  • Fraying

Is your toothbrush looking a bit scruffy? Do those once orderly bristles look like they have the toothbrush equivalent of bed head? Have some bristles vanished altogether? Time to retire that toothbrush. Once the bristles are frayed, you just can’t reach plaque as effectively, especially where it likes to hide between the teeth.

Are you prematurely fraying? You could be brushing too hard. Overbrushing can injure delicate gum tissue, cause wear and tear to tooth enamel, and even damage your braces. If you find your brush fraying after only a few weeks of use, you might be using too much force. Remember, plaque is a sticky film, but it’s a soft sticky film. Ask us for advice on just how hard you need—or don’t need—to brush.

  • Odor

This one really goes without saying—no one wants an aromatic toothbrush! How to make sure your toothbrush is fresh and clean?

Always rinse carefully after you brush. This will get rid of any toothpaste, bits of food, or other particles left on your brush.

Let your toothbrush air dry. It might seem more hygienic to keep your brush covered in a bathroom setting, but a closed, moist container is a perfect breeding ground for germs. Don’t let them make a home in your bristles!

  • Illness

A cold or a bacterial infection (like strep throat) is no fun. But now that you’re feeling better, it might be time to throw out your toothbrush. The chances of re-infection are very low, unless your immune system is compromised, but this is a perfect opportunity to replace your brush with a fresh, germ-free model.

And if you share your toothbrush, or if you store it right next to a family member’s (which you really shouldn’t do, for this very reason), germs get shared, too. Quarantine your brush while you’re ill, and replace it once you’re out and about.

  • Discomfort

Bigger isn’t necessarily better. A brush with a head that’s too big won’t allow you to get into those small spaces in your mouth where plaque likes to collect. And when you are trying to clean around brackets and wires, a regular brush might be a problem. Ask Dr. Allen for suggestions for the best tools for clean and comfortable brushing.

Also, harder doesn’t mean more effective. A brush with hard bristles can cause damage to your gums and enamel. We almost always recommend soft-bristled brushes for this every reason.

There are so many styles of brush out there, you’re bound to find the perfect fit with a little trial and error. Or ask us for suggestions the next time you’re at our San Diego office for an adjustment!

  • You’ve Passed the “Best By” Date

Because of its durable construction, your toothbrush can last a long, long time. But no matter how comfortable and effective your toothbrush is right now, it was never meant to go through life with you. Bristles break down over a period of a few months, and just don’t clean as effectively. Your brush should be changed every three months, and this includes changing the head on your electric toothbrush. And because you wear braces, you’re brushing more often, so that three month lifespan might be stretching it.

Unfortunately, you don’t have a flashing light or annoying beep to remind you when it’s time to change brushes, so you’ll have to devise your own reminders. Reminder apps, calendar notes, the first day of a new season—use whatever works best for you. 

Don’t ignore the clues your toothbrush is leaving you. Replacing your brush whenever it’s necessary helps guarantee that the time you spend cleaning your teeth and gums will lead to confident, healthy smiles. Case closed!

Overbite or Overjet?

January 29th, 2025

The words “overbite” and “overjet” certainly sound similar. Both conditions concern your front teeth. Both conditions fall under the same category of bite problems—Class II malocclusions, if you want to be technical. So it’s not surprising that they’re often used interchangeably. But while there are similarities, overbite and overjet are also distinctly different.

  • Overbite/Overjet Geometry

In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. The key word here is “slightly.” With a Class II malocclusion, the upper front teeth project further beyond the lower teeth than they should.

Of course, teeth and bites are as individual as we are, so there are variations in just how and just how much the overlap occurs. In diagnosing an overbite vs. an overjet, the difference comes down to a matter of vertical vs. horizontal.

An overbite, or deep bite, occurs when the top teeth vertically overlap the bottom teeth more than they should for a healthy bite. Generally, when a person’s top teeth cover more than a quarter of the bottom teeth when biting down, or more than two to three millimeters, that person is said to have an overbite.

An overjet, commonly known as protruding or buck teeth, is the result of a horizontal overlap that is broader than normal. This causes the top teeth to project outward toward the lips more than they do in a typical bite. An overjet is usually diagnosed when the horizontal distance between the top and bottom teeth exceeds two to three millimeters.

  • Overbite/Overjet Causes

The causes for both an overbite and an overjet might be dental (caused by tooth alignment), or skeletal (caused by bone development), or a combination of both. These bite problems can run in families. They are also affected by the size and position of the jaws and the shape and position of the teeth.

Early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use, can also contribute to the development of a Class II malocclusion, particularly an overjet. Consistent pressure from thump or pacifier pushes the teeth outward as they erupt, which encourages them to protrude. These oral habits can affect the shape of the palate and jaw, too.

  • Overbite/Overjet Treatments

There are many types of treatment available to correct teeth and bite misalignments. Dr. Allen will tailor your treatment to your specific malocclusion for the best orthodontic outcome.

If you have a mild malocclusion, and minor dental issues are the main cause of that malocclusion, either braces or clear aligners can be effective for an overjet or an overbite. Elastics (rubber bands) are often used as part of this treatment.

If the malocclusion is due to bite problems caused by uneven upper and lower jaw development, devices called functional appliances can be used with braces to help guide the growth of the jawbones while young patients’ bones are still forming. These include appliances that work inside the mouth to help the upper and lower jaws grow proportionally, and external appliances such as headgear.

In some cases, where the malocclusion is skeletal in nature as well as dental, surgical treatment might be necessary to reshape the jawbone itself. Orthodontic treatment is usually needed as well both before and after surgery.

  • Overbite/Overjet Consequences

Over time, a deep overbite can cause damaged gum tissue, worn enamel, and fractured teeth. When teeth protrude because of an overjet, they can lead to self-consciousness and are more at risk for injury. Both malocclusions share dental and medical consequences, including concerns about facial and jaw appearance, problems speaking or chewing, headaches, and face and jaw pain.

Class II malocclusions aren’t all the same, and orthodontic patients aren’t all the same either. You may have a minor malocclusion or a significant one. You may have an overbite, or an overjet, or a combination of different bite and alignment concerns. Your malocclusion may not bother you at all, or it may cause pain, discomfort, or self-consciousness.

That’s why every overbite or overjet should be evaluated by an orthodontist. When you visit our San Diego orthodontic office, Dr. Allen will be able to diagnose the exact nature of your malocclusion, the reason for it, and your best individualized treatment plan. An overbite and an overjet are different malocclusions, but you and your orthodontist want the same outcome for each: a healthy, attractive, and confident smile!

TMD Problems and How You Can Prevent Them

January 22nd, 2025

Temporomandibular joint disorders (TMD) describe a set of conditions that involve trouble with your jaw and face muscles. They result from a problem in the temporomandibular joint (TMJ), which is a hinge that connects the temporal bones, in your skull in front of each ear, to your jaw. The joint enables you to talk, yawn, and chew by letting your mouth move.

TMD can be very painful and interfere with functions such as eating and speaking. This what to watch for and how to try to prevent TMD.

Risk Factors for TMD

You are at higher risk for TMD if you are a women than if you are male. The disorder is most common among adults between the ages of 20 and 40 years. Other risk factors for TMJ disorders include the following.

  • Arthritis in the area, making movement more difficult
  • Excessive tooth grinding, because it increases stress on the joint
  • General stress, which can lead you to clench your teeth and strain facial muscles

Symptoms of TMD

Symptoms of TMD can last for just a short while, or for several years. Seeing Dr. Allen is important if your symptoms make it impossible for you to eat regularly or if you have unbearable pain or discomfort. The following symptoms can occur on both or one side of your face.

  • Aching or very tired facial muscles
  • Jaws that are fixed open or shut without you being able to unlock them
  • Grating or popping sounds when you chew or close or open your mouth
  • Pain in the entire area, including the mouth, jaw, neck, or shoulders, that comes on when you chew or yawn

Preventing TMD

You can try to prevent TMD by focusing on reducing risk factors. If you grind your teeth at night, ask Dr. Allen about wearing a mouthguard. If you are overly stressed, look into ways to better manage your stress and relax your muscles. Another strategy for trying to prevent the development of TMD is to avoid chewing gum, since that puts stress on your jaw.

If you have questions about TMD, don’t hesitate to contact our San Diego office.

Planning Your Vegetarian Diet with Your Oral Health in Mind

January 15th, 2025

If you’ve been following a vegetarian or vegan diet, you know that there’s much more to living a healthy life than simply avoiding meat products. Making sure your diet includes enough protein, as well as any nutrients that are primarily available in animal products, takes planning, and there’s no one-menu-fits-all solution.

Why? Because there’s no one menu that will suit all vegetarians. Specific vegetarian diets can allow for many different options:

  • Vegan—a plant-based diet which excludes meat, fish, dairy, and egg products
  • Ovo-vegetarian—includes eggs as a dietary option, but no dairy
  • Lacto-vegetarian— includes dairy as a dietary option, but no eggs
  • Lacto-ovo-vegetarian—a meat-free diet which allows both dairy products and eggs

If you are a pescatarian, who eats fish on occasion, or a flexitarian, who sometimes includes meat in a meal, your menu options are even broader.

So let’s look at the big picture—a healthy vegetarian diet is really more concerned with the foods you do eat for nutrition rather than the foods you don’t. You can create a meal plan rich in all your essential nutrients with a little research, no matter which type of vegetarian diet is your go-to choice.

And while you’re constructing your ideal menu guidelines, don’t forget about your dental nutrition!

In terms of keeping your teeth and gums their healthiest, what important vitamins and minerals are often missing from vegetarian and vegan diets? Let’s look at three of them.

  • Calcium

Calcium is essential for maintaining strong bones and tooth enamel. Without enough calcium, a weakened jawbone leads to loose, and even lost, teeth. The acids in our food and the acids created by oral bacteria also weaken the minerals in enamel, including calcium. These weak spots can eventually become cavities. A diet rich in calcium not only supports the bones holding our teeth, but can even help repair, or remineralize, enamel which has been weakened by acidic erosion.

For vegetarians who include dairy in their diets, dairy products are a great way to include calcium. Milk, cheese, and yogurt are traditional and rich sources of this mineral.

For vegans, it’s a bit more challenging, but still doable! Non-dairy foods providing calcium include dark green vegetables (kale, broccoli, spinach), certain types of tofu, and fortified cereals, juices, and non-dairy milks.

  • Vitamin D

Now you’re ready to put that calcium to work by making sure you have enough vitamin D in your diet. Vitamin D not only helps keep our bones healthy, it also enables our bodies to absorb calcium. Bonus—it’s been linked to better gum health in several studies.

So how to get more vitamin D? If you eat dairy, most dairy products have been fortified with vitamin D. If eggs are a part of your diet, egg yolks are a great source. Pescatarians can enjoy the benefits of vitamin D from fatty fish such as tuna and salmon.

Because we get most of our vitamin D from sun exposure or foods derived from animals, plant-based foods are not a practical way to obtain the vitamin D you need. But, just as non-vegetarians can get plentiful vitamin D from fortified dairy products, vegans also have options. Try adding cereals, juices, and non-dairy milks fortified with this essential nutrient to your diet, or take a vegan vitamin D supplement.

  • Vitamin B12

Vitamin B12 is essential for healthy red blood cells, nerve cell development, brain function, and DNA production. (This is why it’s especially important for pregnant and nursing women.) Vitamin B12 can also impact your oral health. A B12 deficiency can cause a swollen, sore, or inflamed tongue, loss of taste, and gum, tongue, and mouth ulcers.

Unfortunately, vitamin B12 is reliably found only in animal foods and nutritional yeasts. If you would prefer an egg-free and dairy-free diet, look to B12 supplements or B12-fortified cereals, plant-based milks, energy bars, and other vegan options. This is a good subject to discuss with your physician, because even supplements and fortified foods might not provide enough B12.

In fact, Dr. Allen can be vital resources when you’re planning your healthiest vegetarian diet. The next time you visit our San Diego office, ask for recommendations for supplements if you’re concerned that diet alone can’t provide for all of your nutrition essentials. Finally, care should be taken to ensure that, even with supplements, you get the proper amount of the vitamins and minerals you need.

As a vegetarian, you are used to the concept of care. Whether it was concern for nutrition, the planet, the animal world, or another reason that drew you to a vegetarian diet, be sure to care for your body as well as your dietary choices. Careful planning can ensure a diet which supports not only your general health, but your oral health, for a lifetime of nourishing—and well-nourished—smiles.
