Can you give me help for sensitive teeth, please help!?

Yes but.. : Proper treatment depends on the nature and severity of the sensitivity. Please visit your dentist for proper care. Special desensitizing agents, including desensitizing toothpaste and Fluoride gel can be applied to the sensitive areas of the affected teeth. Depending on the presentation and if hypersensitivity is severe and persistent, you may require a root canal treatment.

Tooth sensitivity: Is due to the exposure of dentin, the part of the tooth which covers the nerve. The common causes are the result of worn tooth enamel or exposed tooth roots. Other factors, such as a cavity, a cracked or chipped tooth, gum disease or a side effect of a dental procedure. The best way to find out why a tooth is sensitive is to have dental professional examine you and treat.
