Craving that ice cream cone can be frustrating if sensitive teeth stop you every time. Proper sensitive teeth treatment can help you dive back into your favourite flavour. Rather than suffering in silence, discover the main problem, which may be in the exposed parts of your teeth's roots.
The Root Cause
Enamel is a strong natural shield that covers the crown of the tooth, just above the gum line. The roots of your teeth, however, are usually protected by gum tissue, and the slightest bit of receding gum can expose them. Receding gums can be caused by poor oral hygiene, a hard toothbrush and inappropriate brushing technique, teeth grinding and clenching, or even ageing. Below the gum, the root has a very thin protective covering called cementum, but when the most sensitive part of the tooth underneath it – called dentine – is uncovered, your root may become vulnerable over time. When the root is exposed to temperature or fluid changes, the nerve in the pulp can be affected, which leads to sensitivity. So super-hot or cold foods, and even substances that scratch your teeth, can lead to discomfort. In some people, sweet foods can create sensitivity too.
First, consult your dentist to find out what the cause of your gum recession is and whether treatment is required to correct it. Many factors can cause sensitive teeth or make an individual tooth sensitive. Tooth decay, broken fillings, root canal problems, poor oral hygiene, grinding and gum disease can lead to sensitive teeth. Your dentist can conduct an exam and a series of X-rays to determine the cause of your sensitive teeth.
The In-Office Treatment
Sensitive teeth treatment can start in the office, which may involve a cleaning, oral hygiene instruction and the application of a desensitising agent to the exposed areas of your teeth to start the healing process. The desensitising agent enters the sensitive area of the teeth and blocks the dentinal tubules that allow changes in temperature or air to stimulate the nerve fibres in the tooth's nerves (also known as the pulp). These agents include high concentrations of fluoride that sets when it comes in contact with your saliva.
The At-Home Treatments
You can also treat your sensitive teeth at home with the right toothpaste. Some sensitive toothpastes, either prescription or over-the-counter options, may have high enough concentrations of fluoride or other chemicals to reduce sensitivity over time.
Your dentist may also advise you to use a toothbrush designed for use with sensitive teeth. With improved hygiene, tooth sensitivity will usually reverse itself.
Even if you're the most oral-conscious person you know, it's impossible to look at a tooth and identify if it is sensitive. But a sensitive mouth can be successfully treated. A visit to your dentist is the first step, and effective products at home will continue its long-term treatment. Although it may take up to eight weeks for tooth sensitivity to subside, you shouldn't be discouraged from seeking out effective products that are designed to treat sensitive teeth.
