Tooth Pain Causes:
Usually tooth sensitivity (dentin hypersensitivity) presents as temporary tooth discomfort or pain after eating cold food or drink, or breathing in cold air. If the pain is very intense and prolonged, this may be a sign of an unhealthy tooth nerve.
Most commonly, the problem begins when the gums recede. Like a protective blanket, the gums cover the roots of teeth. As gums recede, the underlying tooth roots are exposed. Gums commonly recede for one of two reasons.
- Improper heavy handed brushing of the teeth. It is estimated the 50 - 90% of people brush with too much pressure. Over weeks, months and years of brushing they remove significant gum tissue exposing the tooth roots.
- Poor oral hygiene can lead to plaque build-up around teeth and gums. Over time this plaque hardens into tartar. Bacteria in this tartar are responsible for the gingivitis and periodontal disease that cause gum recession.
The exposed roots contain small pores or tubules which lead directly to the nerve of the tooth. Pain, pressure and cold stimuli can travel down the tubules and trigger the tooth nerve causing pain and discomfort. Normally, the gums cover the tooth root helping to prevent stimuli from reaching these pores.
Sensitivity Prevention:
The obvious answer to preventing tooth sensitivity is to keep the gums from receding. Reducing the pressure we use to brush our teeth helps tremendously. The problem with this is that our tooth brushing is an unconsciously ingrained habit reinforced after decades of brushing and therefore nearly impossible to change. We advise people to use an advanced electric toothbrush (plaque remover). These modern toothbrushes will pay for themselves over time in reduced dental fees. They have built-in features that don't allow you to apply too much pressure while brushing.
Preventing gingivitis and periodontal disease with proper oral hygiene is also crucial in preventing gum recession. Remember, it takes 2 to 3 minutes to properly brush all your teeth surfaces. Most people spend less than 45 seconds brushing, leaving areas untouched where plaque and tartar can build up. Flossing is crucial in order to reach the 35% of the tooth surfaces where brushing can not reach.
How to Treat Sensitive Teeth:
What can you do once you already experience sensitive teeth? Sensitivity toothpastes containing potassium nitrate used daily can help somewhat to reduce tooth sensitivity.The best home remedies for sensitive teeth is to apply a generous amount of potassium nitrate gel directly to the affective tooth area.
A more direct and effective treatment is to apply a potassium nitrate formula directly to the problem teeth by way of a gel brush or cotton swab. Another very effective possibility is a potassium nitrate dispensing pen with built-in applicator brush. The main benefit of the desensitizing pen is it's ability to penetrate into those hard to reach areas and paint on a liberal amount of desensitizing gel to the sensitive tooth.
Additionally:
Watch what you eat. Frequent consumption of highly acidic food and drink can gradually dissolve tooth enamel. Highly acidic foods and drinks (citrus fruits, tomatoes, pickles, soda pop, tea) can increase sensitivity and work against the sensitivity treatment.
