It can start with a simple twinge or be as severe as excruciating pain. From time to time, we have patients asking questions about tooth sensitivity — what causes it? What can be done about it? For these reasons, we have put together the following list of frequently asked questions (FAQs) so that you can develop a healthy understanding about this painful and often avoidable condition.

What is tooth sensitivity?

The first layer of protection of the teeth is enamel. Enamel is a dense crystalline structure, the hardest substance produced by animals. It is an inert substance that has no nerve supply and thus it protects the teeth from temperature and pressure changes. When it is compromised, worn thin, or exposed due to gum recession, it leaves the dentin exposed and vulnerable. Unlike enamel, dentin is living and has delicate nerve fibers within it.

What triggers tooth sensitivity?

Once dentin is exposed, it can become sensitive. It typically occurs when the dentin comes in contact with heat, cold, or the “double whammy” combination of both cold and sweets. Even the bristles of a soft toothbrush can irritate exposed dentin causing sensitivity and pain.

What can be done to minimize tooth sensitivity?

One of the simplest ways to minimize or prevent sensitivity is by teaching proper brushing techniques so that teeth are cleaned without causing either sensitivity or damage. Brushing too hard is a frequent culprit. Being overzealous can literally cause gum recession, leave dentin, and wear it away leaving it grooved. Another step to minimize sensitivity is to use a toothpaste containing fluoride. Fluoride increases the strength of tooth surfaces and thus makes teeth more resistant to attack by acids and sweets. If severe, we may need to apply a barrier to cover the sensitive areas. These barriers may range from concentrated fluoride varnishes to replacing lost tooth structure with filling materials.

There's a lot to like about dental implants, today's state-of-the-art tooth-replacement system. We consider them the best choice for replacing missing teeth because implants are:

Healthy
You may not realize this, but when a tooth is missing, the bone underneath it begins to melt away. That's because bone needs constant stimulation to rebuild itself and stay healthy, and it receives this stimulation from teeth. It's a delicate balance that's disrupted by the loss of even one tooth. Because implants are made of biocompatible titanium, they actually fuse to the bone and prevent bone loss.

Strong
The fusion of implant to bone is an extremely solid connection. Not only does it offer a strong replacement for a missing tooth, but it can also offer support to other tooth-replacement methods such as fixed bridges or dentures. By themselves, these other methods would not preserve bone and might even hasten its loss in the case of dentures. But with implants, bone-loss is prevented — as is embarrassing and uncomfortable slippage of dentures.

Aesthetically Pleasing
When you receive your implant, it is left alone for a few months to complete the fusion process described above. Then it is topped with a crown made of a realistic tooth-like material. The result is so convincing as a tooth replacement, only you and your dentist may be able to tell it's not a natural tooth.

Long-Lasting
Dental implants have an amazing success rate — over 97%. And once they fuse to the jawbone, they should never need replacement. In fact, they will likely outlast the crowns to which they are attached, but this is not a problem. Implant crowns are precision components that detach for easy replacement, should the need arise.

Economical
Implants have a higher initial cost than other forms of tooth replacement, but when you consider how long they last, they are very economical. Consider it an investment in your health, appearance and self-confidence.

If your teeth have a worn appearance, it's possible you have a habit you're not even aware of: clenching or grinding your teeth. Also called “bruxism,” this destructive action causes your top and bottom teeth to come together or scrape past each other with a force that's many times what is normal for biting and chewing.

So what's normal? This can be expressed in terms of pounds. An adult usually exerts a force of 13-23 pounds to bite or chew food. But we have the potential to generate as much as 230 pounds of force, or 10 times what's normal. A “parafunctional” force of this magnitude applied repeatedly is bound to stress your teeth and other areas of your oral system. Besides wearing away the enamel of your teeth — and maybe even some of the softer dentin layer underneath — you may experience muscle spasms or pain in your jaw joints. Serious cases of wear can lead to “bite collapse” in which your face actually changes shape as your cheeks and lips lose support. This can make you look prematurely aged.

What can be done? To prevent further wear, we can fabricate for you a thin, plastic mouthguard that will protect your teeth at night or during times of intense stress. We can also recommend ways to temporarily relieve the discomfort that your grinding/clenching habits can cause. Heat and/or anti-inflammatory medication, for example, can be helpful.

If your tooth wear is minor (raggedness along the biting edge of a tooth or teeth) you may not need any restorative work. However, if tooth wear has already caused changes to your teeth and bite that you find aesthetically or functionally unacceptable, we can restore lost tooth structure in a variety of ways. Veneers and crowns are two examples.

Scientists don't know much about sleep even though it has been extensively studied. We do know that several hours of deep, restful sleep per night are essential for a healthy life.

Many people remain tired and unrefreshed, even after a full night's sleep. About a third of them are affected by sleep related breathing disorders (SRBD). Dentists can play a significant role in helping patients overcome these disorders, which range from frequent snoring to severe Obstructive Sleep Apnea (OSA). If you think you may have such a disorder, read on.

Under normal conditions, your upper airway is open, allowing air to flow from your nose, through your throat, and into your lungs. If you suffer from SRBD, you experience frequent reductions in the flow of air to your lungs during sleep. You may not be aware of it, but sometimes your breathing may even stop for brief periods. These reductions happen when your tongue and other soft tissues in the back of your throat collapse backwards and block your upper airway or windpipe. You may briefly awaken as many as 50 times per night because of these breathing lapses. These brief awakenings, called micro-arousals, keep you from reaching the deep stages of sleep your body needs.

The resulting reduced oxygen flow to your heart and to your brain can cause serious damage. You will also be tired during the day and experience a lack of energy, even if you sleep for seven or eight hours per night. This constant drowsiness puts you at greater risk for accidents.

Because dentists generally see their patients at six-month or other regular intervals, we are in a good position to screen and refer patients with suspected SRBD to physicians for diagnosis and treatment. Dentists can also treat SRBD in a number of ways.

• One of these is Oral Appliance Therapy (OAT), in which a device that looks something like an orthodontic retainer holds your lower jaw in a forward position relative to your upper jaw, preventing your tongue and soft tissue from collapsing into your airway.
• Another consists of breathing equipment called Continuous Positive Airway Pressure (CPAP). The CPAP is a mask connected to a machine that pushes air into your lungs.
• Other treatments include oral surgery or orthodontia. The goal of these techniques is to increase the volume of air passing through your upper airway by pushing your tongue forward.

Medical insurance usually covers the cost of much of these treatments.

Dental professionals agree that effective removal of plaque, the film of bacteria (also called a biofilm) that gathers on everyone's teeth, is the key to good dental health. Daily brushing and flossing are the usual recommendation for plaque removal. It is important to ask us about effective brushing and flossing. At your next appointment, ask us for a demonstration.

Effective brushing removes plaque from the easily accessed surfaces of the teeth. To remove plaque from between the teeth, you must floss.

Some people find it awkward to hold the floss with their fingers as they move it around their teeth. One technique for flossing, suggested by a dentist in Dear Doctor magazine, may make it easier than more traditional methods, although it does take a little practice.

Preparation
This method requires tearing off a 10 to 12 inch length of floss and tying it to form a circle big enough for your fingers, but not your thumbs, to fit within it. The circle should be knotted with a double knot.

To Clean Teeth and Gums
Keep the floss taut at all times, with about and inch or less between your thumb and index fingers for your upper teeth, or index fingers only for your lower teeth. Curve the floss around each tooth and gently move it up and down until you hear a squeaky clean sound. Extend the downward movement of the floss to just below the surface of the gum, without being too harsh and causing injury. As you move from tooth to tooth, move around the floss circle so that each tooth gets a clean section of floss.

Upper Teeth
Place all your fingers in the ring, with the floss over your left thumb and right index finger to floss your upper left teeth, and over your right thumb and left index finger to do the other side.

Lower Teeth
Use both index fingers to floss all your lower teeth.

You may only need to floss once a day before or after brushing to keep your gums health and ward off periodontal (gum) disease. Your dentist will guide you as to how often you may need to floss your teeth. Try this technique and see how it works for you.
