Something can be done about sensitive teeth which can arise from acid attack, grinding and tooth brush abrasion.
You may develop sensitivity when the protective enamel is disrupted and wears away to expose the dentine layer underneath. That’s the layer you feel if you didn’t have anaesthetic with your fillings. It’s made up of lots of little pipes that contain fluid and nerve endings. When different temperature liquids run across these tubules or this tooth structure is touched it causes a jolt of pain. This pain is generally relieved shortly after the stimulus is removed.
Most desensitizing toothpaste utilises chemistry that aims to block these tubules, with some working better than others. The latest research is showing that calcium and phosphate, minerals that exist in teeth, work best to block these tubules. These minerals are available in tooth mousse by GC. Colgate has also released some new independent research that shows its Arginine chemistry in Pro-Relief toothpaste is very effective at desensitizing and remineralizing tooth structure.
If you apply these to teeth daily for about 4 weeks you can have relief from that cold pain.
