Tooth sensitivity is an issue that can range from a slight twinge at times to downright excruciating pain. However, before we continue, understanding the cause of tooth sensitivity is helpful to both relieving and treating it.

Tooth enamel is inert in that it has no nerve supply and thus it protects the teeth from temperature and pressure changes — the main cause of sensitivity. Once it is compromised, worn thin, or exposed due to gum recession, it leaves the delicate nerve fibers within the dentin vulnerable to touch, acid, and temperature change. These nerve fibers most often grab your attention when they come in contact with heat, cold, or a “double whammy” combination of both cold and sweet. They also become sensitive to touch — even the bristles of a soft toothbrush can irritate exposed dentin.

As for the causes of tooth sensitivity, one common cause we see is aggressive brushing. Yes, too much brushing can be bad for you! To be more specific, excessive, improper brushing with a sawing back and forth motion can erode the gum tissues, expose, wear, and even groove the dentin. Another cause for sensitivity can be from the destructive process of tooth decay that eats through the enamel and into the dentin.

When it comes to your oral healthcare, we strive to provide state-of-the-art care along with education to both our patients and community. One way we do this is by taking a moment to answer some of the questions we are most often asked about a certain topic. And one topic that almost always ignites questions is the subject of lumps and bumps in the mouth.

Help! I just found a small lump in my mouth — what should I do?
Not to alarm you, but your first priority is to contact us as soon as possible to schedule an appointment so that we can review it. Most often, we will know what it is by taking a history, knowing how long it's been there and what it looks like. Depending on what we find, we may want to take a biopsy so that we can determine exactly what it is and how we need to treat it.

What is involved in having a biopsy performed?
A biopsy is a normal and routine procedure that is used to definitively diagnose and confirm exactly what the abnormal lump, bump or other tissue is. It is typically performed with local anesthesia so that a small tissue sample can be removed without any pain for examination under a microscope. Depending on the size of the wound, it may require two to three sutures (stitches), leaving a flat and flush surface that heals in a few days to a week. The procedure usually lasts between 10 and 15 minutes with the lab results processed within a few days.

Does this mean I have cancer?
No, the chances are slim that you actually have cancer. However any change or sore in the mouth that does not heal in a week or two should be evaluated by a dentist and if necessary biopsied. If it is pre-cancerous and removed, it could save your life. The most important fact you need to remember is that no one can tell for sure what the abnormal tissue growth is until an expert in oral pathology (“patho” – disease; “ology” – study of) examines it under a microscope. While it is human nature to be concerned, until you have the facts, you are suffering needlessly.

You may have noticed, as you get older, that the enamel of your teeth is looking worn in certain areas. Sometimes tooth wear takes the form of a minor chipping or fracturing at the incisal (cutting) edges of the teeth, or a loss of tooth material from the area near the gum line. In more severe cases, worn teeth look quite a bit smaller than they used to. Why does this happen?

Some wear with age is natural. But too much wear can interfere with your bite, expose more sensitive inner parts of the tooth to decay, and give you a more aged appearance.

There are things you can control that affect wear:

Your habits: Clenching or grinding habits, also called “bruxism,” is a major cause of tooth wear. The motion of teeth sliding over each other with forces that are beyond what's normal for biting or chewing causes a mechanical removal of tooth enamel. This can happen during sleep or periods of high stress. In either case there are therapies available, such as a thin, professionally made mouthguard that prevents your teeth from coming into contact with each other. Holding foreign objects, such as nails and bobby pins, between your teeth can also cause wear.

Your diet: Tooth enamel can be eroded (dissolved away) by acidic beverages, such as sodas, sports drinks and juices. Frequent snacking on sugary foods encourages the growth of oral bacteria that produce acid as a byproduct — also leaving your teeth vulnerable to tooth decay. Your saliva can buffer the effects of the acid in your mouth in about half an hour; if you consume these types of foods and beverages continually, there won't be enough time for this to work.

We can restore the appearance and function of worn teeth in a variety of ways. Porcelain crowns and veneers, for example, can re-establish the normal thickness and length of teeth while improving their color and giving you a more youthful appearance.

A pregnant woman has a lot to think about while preparing to welcome a new member of her family. It's important to think about her oral health as well. She is sharing her body with the developing infant, so problems with her health — including her dental health — can affect the baby. The following facts will help you understand the relationship between oral health and pregnancy.

1. A baby's primary (baby) teeth begin to form during the sixth week of pregnancy. They begin to form their enamel (the hard outer layer of the teeth) and dentin layer (just under the enamel) at about the third or fourth month. The calcium, phosphorous, and protein that are needed for these structures must all be provided by the mother's diet.
2. A good diet for a pregnant mother, in order to provide for both her needs and those of the fetus (the developing baby), includes whole grains, fruits, vegetables — including green leafy vegetables — proteins and dairy products. A doctor may also recommend iron and/or folic acid supplements.
3. If the mother's diet does not provide enough calcium for the baby's bones and teeth, it will come from calcium stored in her bones — not from her teeth. The old idea that a mother's teeth lose calcium during pregnancy has been found to be a myth.
4. Progesterone, a normal female hormone, is elevated during pregnancy. This hormone stimulates production of prostaglandins, substances that cause inflammation in gum tissues if the bacteria that cause periodontal (gum) disease are present. The resulting swelling, redness, and sensitive gum tissues, called pregnancy gingivitis, are common during the second to eighth months of pregnancy.
5. The bacteria involved in periodontal disease can affect whole body conditions such as heart disease and strokes, diabetes, and respiratory diseases. The inflammation resulting from such bacteria can also cause premature delivery (birth before 37 weeks of pregnancy) or low birth weight in the baby.
6. Periodontal disease is also related to pre-eclampsia, or high blood pressure, during pregnancy.
7. Dental x-rays do not expose the mother to very high radiation, but in any case every precaution is taken to minimize exposure to the fetus. These include a leaded apron that shields the baby from exposure.
8. Most drugs commonly used in dentistry, including local anesthetics, can safely be given to pregnant women without affecting the fetus. However, it is important to let your dentist know you are pregnant before embarking on any treatment to make sure anything that is done will be safe for the fetus and its developing teeth.

When dentists talk to patients, they often use specialized vocabulary referring to various dental conditions. Do you understand what they mean when they use these words — or are you wondering what they are talking about?

Here's your chance to test your knowledge of ten words that have a particular meaning in the context of dentistry. If you already know them, congratulations! If you don't, here's your chance to learn what these words mean in the dental world.

Enamel
In dentistry, enamel is the hard outer coating of your teeth. It is the hardest substance produced by living animals. It is a non-living, mineralized, and composed of a crystalline form of calcium and phosphate.

Dentin
The dentin is the layer of a tooth that is just beneath the enamel. It is living tissue similar to bone tissue.

Pulp
When dentists speak of pulp, we mean the tissues in the central chamber of a tooth (the root canal) that nourish the dentin layer and contain the nerves of the tooth.

Bruxism
Many people exert excess pressure on their teeth by clenching or grinding them. This is called bruxism, a habit that can be very damaging to teeth.

Occlusion
By this we mean how the upper and lower teeth are aligned, and how they fit together. This can also be referred to as your bite.

Dental caries
This term refers to tooth decay. Dental caries and periodontal disease (see below) are two of the most common diseases known to man. Today, these diseases are not only treatable, but they are also largely preventable.

Periodontal disease
A term for gum disease, this term comes from “peri,” meaning around and “odont,” meaning tooth. It is used to describe a process of inflammation and infection leading to the progressive loss of attachment between the fibers that connect the bone and gum tissues to the teeth. This can lead to loss of teeth and of the bone itself.

Erosion
When you consume acidic foods or drinks, the acids in your mouth react directly with minerals in the outer enamel of your teeth, causing chemical erosion. This is not the same as tooth decay, which is caused by acids released by bacterial film that forms on your teeth (see below).

Dental implant
A dental implant is a permanent replacement for a missing tooth. It replaces the root portion of the tooth and is most often composed of a titanium alloy. The titanium root fuses with the jaw bone, making the implant very stable. A crown is attached to the implant and can be crafted to match your natural teeth.

Plaque
Dental plaque is the whitish film of bacteria (a biofilm) that collects on your teeth. Your goal in daily brushing and flossing is to remove plaque.
