Tooth sensitivity

I was wondering if anyone had suggestions for toothpastes and mouthwashes for sensitive teeth? My teeth are especially sensitive to hot and cold. Thanks in advance!

Hi Lehcarssim!

You should visit your dentist to check if you are free from any gum disease. Gum recession causes extreme teeth sensitivity. You can ask him for toothpaste with fluoride, which is good for sensitive teeth. Mine was treated with fluoride varnish.

Hello there!

You should consult your dentist. He will look what causes the sensitivity and from there, he will prescribe the course of action. If you are free from gum disease or tooth decay, then fluoride treatment is likely recommended.

Generally, teeth become sensitive when the gums recede exposing the tooth roots. Gums recede if you are brushing too hard or if you have periodontal disease. Keep your gums from receding to prevent tooth sensitivity. Use toothpaste with potassium nitrate and fluoride mouthwashes. These can help reduce tooth sensitivity. You can acquire them from your dentist.

Sensitive teeth occur when the underlying layer of your teeth -- the dentin -- becomes exposed as a result of receding gum tissue (the protective blanket that covers the tooth roots). The roots, which are not covered by hard enamel, contain thousands of tiny tubules leading to the tooth's nerve center (the pulp). These dentinal tubules (or channels) allow the stimuli -- for example, the hot, cold, or sweet food -- to reach the nerve in your tooth, which results in the pain you feel.

There are many factors that may lead to sensitive teeth, including.

Brushing too hard. Over time, brushing too hard or using a hard-bristled toothbrush can wear down enamel and cause the dentin to be exposed. It can also cause recession of the gums (the gum tissue pulls away from the teeth).

Tooth decay near the gum line.
Recession of the gums. As gums move away from a tooth due to conditions such as periodontal disease, the root surface becomes exposed.
Gum disease (gingivitis) . Inflamed and sore gum tissue may cause sensitivity due to the loss of supporting ligaments, which exposes the root surface that leads directly to the nerve of the tooth.
Cracked teeth. Chipped or broken teeth may fill with bacteria from plaque and enter the pulp causing Inflammation.
Teeth grinding . Grinding or clenching your teeth may wear down the enamel and expose underlying dentin.
Tooth whitening products. These products may be major contributors to sensitive teeth.
Your age. Tooth sensitivity is highest between the ages of 25 and 30.
Plaque build-up. The presence of plaque on the root surfaces can cause sensitivity.

OTC toothpastes like Sensodyne and Denquel have potassium nitrate as their activity ingredient, and help a little over time.

One step further:You can have your dentist fabricate trays, and fill them with fluoride or calcium phosphate solutions like MI paste.

Still further- If you can identify specific teeth that are super sensitive, your dentist can treat the root surfaces with penetrating resins.

This is assuming your sensitivity is due to exposed roots, and not cavities.
