It is not uncommon to have one or more teeth that are particularly sensitive to heat, cold, or pressure. If you have such a tooth, you probably want to know what caused it and what you can do about it. Here are some frequently asked questions, and their answers.
What causes teeth to become sensitive?
The most common cause of sensitivity is exposure of the tooth's dentin, a layer of the tooth's structure that is just below the outer protective layer (the enamel).
The dentin is sensitive but the enamel layer is not. Why?
The enamel is composed of minerals that are hard and protective. It is not living tissue and has no nerve supply. The dentin layer underneath is bone-like living tissue that does contain nerve fibers. It is protected by enamel above the gum line and by gum tissue in the area of the tooth's root, below the gum line. If the tooth's protective covering is reduced, the nerve fibers in that section of the dentin are exposed to changes in temperature and pressure, which they conduct to the inner pulp layer (nerve) of the tooth. The sensations that reach the tooth's interior pulp layer cause pain.
What causes exposure of the dentin layer in teeth?
Often the dentin is exposed by receding gums, causing areas of the tooth that are normally below the gum surface to be uncovered.
What makes gums recede?
One cause of receding gums is excessive, rough brushing techniques. This is particularly common in individuals who have a family history of thin gum tissues. Removing the film of bacteria called plaque requires only gentle action with a soft brush. This is one reason that we stress the value of learning proper and effective brushing techniques. Gum recession becomes worse after the uncovered dentin of the tooth's root is exposed to erosion from sweet and acidic foods and beverages, such as fruit juices.
Doesn't tooth sensitivity indicate decay?
Decay can also cause tooth sensitivity. As decay destroys a tooth's structure, it eventually invades the inner pulp of the tooth, causing greater and greater pain.
How can you prevent or reduce tooth sensitivity?
As we mentioned above, learn proper brushing techniques; we would be happy to demonstrate them. Use a toothpaste that contains fluoride, which increases the strength of the tooth's protective coating. In more serious cases, we can apply a fluoride varnish or a filling material as a barrier to cover sensitive areas. If you experience long-term tooth sensitivity, make an appointment for an assessment and diagnosis so that we can determine the cause and proper treatment.
Witnessing or being involved in a sports-related dental injury can be a scary event not only for the player, but also for onlookers even if the injuries turn out to be minor. However, knowing what to do — and more importantly — how quickly to react can make a radical difference to the outcome. This is just one reason why we want to share the following easy-to-remember guidelines for what, how and when you need to respond to various types of dental injuries.
- Immediate — within 5 minutes of the injury: If a permanent tooth is totally knocked out (avulsed), it requires immediate treatment by cleaning and re-implanting the tooth back into its original position to have any hope of saving the tooth long-term. Knocked out baby (primary) teeth are not reimplanted for fear of damage to underlying permanent teeth.
- Urgent — within 6 hours of the injury: If a permanent or primary tooth is still in the mouth but has been moved from its original position, it is considered an acute injury and should be treated within 6 hours.
- Less urgent — within 12 hours of the injury: If a permanent or primary tooth is broken or chipped but has not shifted from its original position, the injury is classified as less urgent. You still need to see a dentist for an exam; however, you generally can wait up to 12 hours before possible irreversible damage occurs.

We pride ourselves on educating our patients regarding oral health and dental treatment. This is why we are providing you with these frequently asked questions (FAQs) regarding root canals. Our belief is that by being informed about this important dental treatment, you will be more comfortable should you ever require a root canal.
Exactly what is root canal treatment?
A root canal treatment is an endodontic procedure (“endo” – inside: “dont” – tooth) in which the living pulp tissues are housed, including the nerves. When a severely decayed or damaged tooth begins to hurt, it is because the pulpal tissues are inflamed or infected, and the response of the nerves is varying degrees of pain — letting you know something is wrong. If the pulp is dead or dying it must be removed and the root canal of the tooth is filled and sealed to stop infection and to save the tooth.
Who typically performs them?
Endodontics is a specialty within dentistry that specifically deals with the diagnosis and treatment of diseases and disorders of root canal issues affecting a tooth's root or nerve. While endodontists are dentists who specialize in root canal treatment, general dentists may also perform root canal treatment and are usually the dentists you will consult with when you first have tooth pain and who will refer you to an endodontist if necessary.
What are the symptoms of a root canal infection?
Root canal symptoms and the character of the pain may vary depending on the cause. For example, symptoms may be:
- Sharp, acute pain that is difficult to pinpoint
- Intense pain that occurs when biting down on the tooth or food
- Lingering pain after eating either hot or cold foods
- Dull ache and pressure
- Tenderness accompanied by swelling in the nearby gums
Does root canal treatment hurt?
A common misconception is that a root canal treatment is painful when, in actuality, it is quite the opposite. The pain associated with a root canal occurs prior to treatment and is relieved by it — not visa versa.
If you have tooth pain, you may or may not need a root canal treatment. Contact us today (before your symptoms get worse) and schedule an appointment to find out what's causing the problem.

We've all heard of morning sickness, but did you know that it's also not unusual for pregnant women to experience oral discomfort? This is what Entertainment Tonight co-host Nancy O'Dell discovered when she was expecting her daughter, Ashby. In an exclusive interview with Dear Doctor magazine, Nancy described how her gums became extra-sensitive during pregnancy, leading her dentist to diagnose her with “pregnancy gingivitis” (“gingival” – gum tissue; “itis” – inflammation).
“While my dental health has always been relatively normal, pregnancy did cause me some concern about my teeth and gums,” Nancy said. “With my dentist's advice and treatment, the few problems I had were minimized,” she said.
It's especially important to maintain good oral hygiene during pregnancy with routine brushing and flossing, and regular professional cleanings. This will reduce the accumulation of the dental bacterial plaque that leads to gum disease. Both mother and child are particularly vulnerable to these bacteria during this sensitive time. Scientific studies have established a link between preterm delivery and the presence of periodontal (gum) disease in pregnant women. Also, the elevated hormone levels of pregnancy cause the tiny blood vessels of the gum tissues to become dilated (widened) and therefore more susceptible to the effects of plaque bacteria and their toxins. Gingivitis is especially common during the second to eighth months of pregnancy.
Excess bacterial plaque can occasionally lead to another pregnancy-related condition in the second trimester: an overgrowth of gum tissue called a “pregnancy tumor.” In this case, “tumor” means nothing more than a swelling or growth. Pregnancy tumors, usually found between the teeth, are completely benign but they do bleed easily and are characterized by a red, raw-looking mulberry-like surface. They can be surgically removed if they do not resolve themselves after the baby is born.
