Psst—here’s some time sensitive information just for you. If your teeth are sensitive to heat, cold, sweets, acidic foods, wind and/or air, it could mean it’s time to see your dentist!

Normally, we don’t notice how external conditions affect our teeth at all. Tooth enamel—the hardest substance in the body—protects the inner tooth from outside stimuli. So, why do strong, solid teeth suddenly feel sensitive? The answer’s found in tooth anatomy.

The crown of the tooth, the part we can see above the gum line, has three distinct layers.

• Enamel, a strong mineral-rich coating, surrounds the outside of each tooth and protects the dentin and pulp inside.
• Dentin is the softer, porous middle layer of the tooth. Dentin contains thousands of tiny, fluid-filled tubules which extend to the pulp.
• In the center of each tooth is the pulp chamber, filled with nerves, blood vessels and connective tissue which keep the tooth alive and healthy.

The roots below the gumline have a similar structure, with one important exception.

• Cementum, which is not as hard and strong as enamel, covers the root surface instead of enamel.

Healthy, undamaged teeth allow you to enjoy an icy beverage, a hot latte, a sweet treat, or a brisk walk without any dental discomfort.

When the tooth’s protective enamel covering is worn or damaged, the dentin below the enamel is exposed to external conditions. Temperature changes, air, wind, sweets and acids—all the stimuli which normally have no effect on our teeth are now transmitted through the dentin’s tubules to the nerves inside the pulp.

The pulp’s nerves respond to these sensations by sending out pain signals. The uncomfortable tooth sensitivity which results is often described as an annoying twinge, a sharp, brief stabbing pain, or a shocking sensation.

The first step in treating dentin exposure is to see your dentist to discover the cause. Tooth sensitivity could be the result of:

Aggressive Brushing

Brushing is great! Over-aggressive brushing? Not so much. Heavy-handed brushing and brushing with anything other than a soft-bristled brush can wear down mineral-rich tooth enamel to expose the dentin underneath, and is even more damaging to less-mineral-rich cementum.

Diet

An acidic or sugary oral environment harms enamel. Consuming acidic foods and beverages erodes the minerals which make enamel so strong. Sugars give plaque bacteria the perfect fuel they need to produce enamel-eroding acids.

Cavities

The bacteria in plaque create acids which strip minerals from tooth enamel. Over time, a hole in the enamel develops, uncovering the sensitive dentin below.

Injuries

A crack or fracture can expose dentin, or, in severe cases, tooth pulp, to foods, heat, cold, and air.

Tooth Grinding

Bruxism, or tooth grinding, often takes place during sleep, and can apply over a hundred pounds of pressure to the teeth and jaws. Continuous grinding and clenching wears away tooth enamel, exposing dentin. Bruxism can also cause chipped and cracked teeth, as well as jaw damage and even tooth loss.

Malocclusion

Occlusion refers to the way our teeth and jaws fit together. In a healthy occlusion, the forces of biting and chewing are evenly distributed. A malocclusion, or bad bite, can cause excessive or uneven pressure on teeth and jaws, leading to worn enamel, cracked teeth, and more serious bite problems.

Just as there are many causes for tooth sensitivity, your dental team in Fresno, CA has many solutions to restore your comfortable, healthy smile.

Choose the Right Products to Protect Your Smile

• If you’re not using a soft-bristled brush, trade in your old model ASAP, or try an electric toothbrush. Bonus: Electric toothbrushes and water flossers can be especially helpful for cleaning around your braces!
• There are special toothpastes which are formulated to reduce sensitivity.
• Fluoride treatments can help strengthen tooth enamel.
• Talk to your orthodontist, dentist, or hygienist to learn the best ways to brush and the best products to use to protect your dental health and your tooth enamel.

Eat a Dental-Healthy Diet

• Cut down on acidic and sugary foods and drinks to protect your tooth enamel. And, of course, stick with your braces-healthy diet by removing sticky, crunchy, hard, and chewy items from the menu.
• Check ingredients. The amount of acids and sugars in foods like sodas and sports drinks could surprise you!
• If you do eat something acidic, don’t brush right away—rinse with water and wait an hour to give your enamel time to restrengthen and remineralize.

See Your Dentist Regularly

• Regular exams will discover any cavities before they become deeper and more damaging. Proactive care will also help keep your orthodontic treatment plan on track.
• Gum disease can cause gum recession, exposing those sensitive, cementum-covered roots. Your dentist will look out for any signs of early gum disease and offer tips for gum health.
• If you suspect you have an injured tooth, call Dr. Robert Kubo and Dr. James Kubo immediately to prevent more serious damage or infection.

Protect Your Smile from Trauma

• A custom-fitted nightguard can prevent enamel erosion and other damage caused by bruxism.
• Wear a mouthguard when playing contact sports or activities to protect your teeth from injuries.
• If you’re wearing traditional braces, your dentist can customize a nightguard or mouthguard which will work with your braces.

Create a Healthier Smile with Orthodontic Treatment

• If you suspect a bite problem is causing wear on your teeth, it’s time for an orthodontic consultation with Kubo Orthodontic Group! Orthodontic treatment aligns the teeth and jaws properly, which means that your teeth will fit together without causing any extra wear on your enamel or exposing the sensitive dentin underneath.
• Preventing worn enamel is, of course, only one benefit of orthodontic treatment. Properly aligned teeth reduce the risk of cavities. Treatment can prevent dental injuries caused by excess pressure and stress. And there’s no underestimating the value of a confident, healthy smile!

If you’re feeling sensitive, especially if discomfort persists or worsens, see your dentist to discover the cause of the problem. Tooth sensitivity is time sensitive. Take care of small problems before they become serious ones, and you’ll help make sure your smile is something you’re not the least bit sensitive about!

If you’ve visited Kubo Orthodontic Group, then there’s a good chance you’re looking to perfect your smile by straightening your teeth with braces. At some point during your treatment, you may need to use elastics, otherwise known as rubber bands, for a certain period. These are used to apply additional pressure that will move your teeth in the right direction.

Placement of the elastics is specific to each patient’s teeth. These small rubber bands stretch over the tiny loops on both the top and bottom brackets. At first, Dr. Robert Kubo and Dr. James Kubo may recommend you wear the elastics both day and night for an extended time.

You may be told to switch only to nighttime wear once the teeth are set in the correct position. By consistently wearing the elastics, you can shorten the overall time your braces will have to be on.

The elastics are made from medical-grade latex. If you have an allergy to latex, make sure to let Dr. Robert Kubo and Dr. James Kubo know, so you can be given an alternate material. We will show you how to take elastics on and off when they’re given to you at your appointment.

You should remove them when you eat so they don’t become overstretched or break. It’s important not to overstretch the bands, and always to replace them if they break. Eventually it will become a familiar habit to carry the bands around with you for times when this might happen.

The Do’s and the Don’ts

• DO … always wash your hands before removing or replacing the rubber bands.
• DO … call us if you run out of elastics.
• DO … get in the habit of carrying around extra rubber bands as replacements.
• DON’T … double up on elastics because this can exert too much pressure on your teeth and could actually harm the roots.
• DON’T … overstretch the rubber bands or they will lose strength and become ineffective.

If you were recently given elastics as well as your braces, feel free to ask any questions during your appointment, or call our Fresno, CA office any time. Using elastics correctly is one more step in your journey to a perfect smile!

Some foods are just terrible for your teeth — think cookies and candy bars — but there are certain foods that are beneficial to your oral health. Below, Dr. Robert Kubo and Dr. James Kubo and our team have covered five of the top foods to keep your teeth and gums healthy!

1. Crispy, low-acid fruits and vegetables: Fruits like apples and vegetables such as carrots and celery act like “natural toothbrushes,” helping to clear plaque from your teeth and freshen your breath.

2. Kiwis: These little green superstars are packed with vitamin C which is essential for gum health. The collagen in your gums is strengthened when you consume foods that are high in vitamin C, like kiwis, thus helping to prevent periodontal problems.

3. Raw onions: Onions have long been studied for their antimicrobial, antibacterial, and antioxidant properties. Proliferation of bacteria is what leads to tooth decay and cavities. By including raw onions in your diet, you'll be doing your part to wipe out those little microbes before they can multiply!

4. Shiitake Mushrooms: A specific compound in shiitake mushrooms, lentinan, has been shown to have antibacterial properties that target the microbes that cause cavities while leaving other beneficial bacteria alone. It may also help prevent gingivitis, or inflammation of the gums.

5. Green Tea: Often lauded for its high antioxidant content and many health benefits, it turns out green tea also benefits your oral health! A Japanese study found men who drank green tea on a regular basis had a lower occurrence of periodontal disease compared to men who drank green tea infrequently. It's believed this is due to the catechins in green tea, a type of flavonoid that may help protect you from free radical damage, but more research needs to be done. Either way, drink up for your overall health, as well as your teeth!

Most people think braces are all about their teeth. While it is true orthodontics is meant to move your teeth into proper position, there's more to it than that. To safely move your teeth with braces, you're going to need healthy and stable gums (or periodontium—the tissues that support your teeth).

For this reason it's critical to have your periodontal health evaluated prior to getting braces. This applies particularly to adults, since a 2013 study by the Center For Disease Control found that an estimated 47.2% of adults 30 years of age and older had periodontitis (gum disease). If you do have periodontitis, moving your teeth with braces will only make things worse.

Conversely, there is also risk for periodontal disease if you don't get orthodontic treatment. Malocclusion, as well as crooked and spaced teeth, can all contribute to periodontal disease. In these situations your teeth and gums are more difficult to clean and become breeding grounds for disease causing bacteria. Bad oral hygiene combined with these traits can greatly contribute to the development of periodontitis.

So, periodontics and braces have a tricky relationship. On one hand, you shouldn't get braces if you show signs of developing or have periodontitis, while on the other hand, braces can help prevent the possibility of developing periodontitis by correcting the bite and straightening the teeth.

If you are 30 years of age or older and are considering getting braces, it would be wise to first:

• Let Dr. Robert Kubo and Dr. James Kubo know about your desire to get braces
• Get an exam to make sure you're in good periodontal health and a good candidate for braces
• If you are a good candidate, keep an eye on your teeth and gums and get regular dental checkups throughout your entire course of treatment.

If you are in any doubt about the status of your teeth and gums, it's always best to get them checked before embarking with braces treatment. For more information or to have your periodontal health assessed for braces treatment, please contact our Fresno, CA office.
