Take the Scream Out of Ice Cream
“We all scream for ice cream,” the saying goes. But what if eating ice cream — or any very cold or hot food — literally makes you want to scream because your teeth hurt so much?
What causes sensitivity in teeth?
Understanding the anatomy of a tooth helps explain what happens when a tooth becomes sensitive to heat and cold. A tooth is composed of three types of tissue: a hard outer shell of enamel, the body of the tooth composed of the dentin, and an interior tissue of the pulp.
Enamel: The enamel forms the outside of the crown, the part of the tooth you normally see. Made of densely packed crystals of calcium, it is resistant to wear. It is not living tissue, and does not contain nerves, but it is capable of transmitting temperature like hot and cold.
Dentin: Inside the tooth’s crown and root is a living tissue called dentin, which is a porous structure similar to bone. It is composed of microscopic tubules containing living cells, which are encased in a hard substance made of calcium crystals.
Pulp: The living dentin transmits sensation through to the pulp, which is in the center of the tooth and contains the tooth’s blood vessels and nerves.
A tooth’s enamel normally protects the dentin from exposure to extremes of temperature and pressure. If you wear away the enamel and expose the dentin, it will pass sensation through to the nerves in the pulp more directly. The result can range from a twinge to an excruciating pain.
Sensitivity can be caused by:
- Overzealous tooth brushing resulting in enamel wear and consequently dentin exposure and wear.
- Enamel and dentin erosion by acids in the foods and beverages you eat and drink.
- Tooth decay — the most common cause of sensitivity. Decay destroys enamel and dentin inflaming and infecting the living tissues of the pulp, which become increasingly painful.
What can you do to make your teeth less sensitive?
- Use a soft bristle tooth brush, and brush the affected teeth gently to remove all bacterial plaque. We can advise you on safe and effective brushing techniques.
- Use toothpaste that contains fluoride. Fluoride strengthens tooth surfaces and makes them more resistant to sensitivity and decay.
- Ask us about professionally applied fluoride varnishes or filling materials that can cover and replace sensitive or lost tooth structure.
Of course, if the problem is caused by tooth decay, make an appointment with us to remove the decay and place a filling in the sensitive teeth.

Signs and Symptoms of Oral Cancer
No one wants to hear the word “cancer.” But thanks to advances in detection and treatment, the disease increasingly can be stopped in its earliest stages when it’s most treatable and outcomes are most favorable. Oral cancer accounts for a relatively small 3% of cancers in men and 2% in women, but early detection rates are lagging. Our office screens for oral cancer as part of your regular checkups. Knowing some of the signs and symptoms can help you monitor as well.
The main areas where oral carcinomas (cancers) occur are:
- the tongue (most common location, particularly the sides and on the floor of the mouth),
- the lip (especially the lower one),
- the oral cavity (the mouth), and
- the pharynx (back of mouth and throat).
Early Signs
Most oral cancers are preceded by surface changes (lesions) of the oral membranes. In the “precancerous” stage, white or red patches start forming and a non-healing ulcer may appear. The most common locations on the tongue for this to occur are on the sides and underneath on the floor of the mouth. Lip cancers typically develop on the lower lip, usually in people with a history of sun exposure. There has often been prior damage at the site such as scaling and crusting.
Be aware that oral cancers can be mistaken for cold and canker sores, ulcers, minor infections, and even irritations caused by biting or certain types of food. If lesions don’t heal within two or three weeks, there’s a higher likelihood that they are cancerous.
An in-office examination includes the following:
- visual inspection of face, lips, neck and mouth;
- inspection of sides and underneath of tongue and floor of mouth using gauze to gently manipulate the tongue;
- palpation of the floor of the mouth, sides of neck and glands to detect unusual lumps; and
- an “open wide and say ‘Aah’” examination of the back of your throat.
There are some risk factors for oral cancer that can’t be controlled, such as a family history, age and race. But awareness, monitoring for potential signs and seeking prompt attention are always key ingredients in protecting your oral health!

Oral Piercings — Tongue & Lip Bolts: Trendy But Dangerous
Tongue and other piercings are a current fad or trend, but can often lead to unforeseen problems.
Piercing the tongue and installing a metal ornament called a tongue bolt commonly leads to chipped teeth, sensitivity, and pain. More frequently, it can cause problems with the gums, such as recession, inflammation, infection, bone loss, and even nerve damage.
In one case reported by the American Medical Association, a teenager suffered 20 to 30 daily electrical shocks in many areas of her face after having her tongue pierced and installing a tongue bolt. A neurologist found that the bolt irritated the nerves to her tongue, causing the symptoms. After the bolt was removed, the shocks and symptoms ceased and her tongue healed.
Having the bolts placed may be painful. The tongue is rich in nerves and blood vessels and a lot of bleeding can occur, which can be difficult to stop. Think about how painful it is when you bite your tongue or lip accidentally. And tongue and lip bolts are not generally placed by health professionals or under sterile conditions.
If you are considering getting an oral piercing, make an appointment with us to discuss all the possible ramifications before you make the decision to go ahead. If you already have an oral piercing, be sure to come in for frequent checkups.
