3. Acidic mouthwash

Be careful about the type of mouthwash you use to clean your mouth. Acidic mouthwash, just like acidic foods, can also erode the tooth enamel. If you have a mild sensitivity, long-term acidic mouthwash can worsen the condition.

Your cosmetic dentist will always advise that you limit the use of whitening products. Using teeth whitening products for a long time will erode the tooth enamel and result in insensitivity. 

Teeth whitening products contain added chemicals that, in most cases, are tough on the tooth enamel and can wear down with time. If you must use the whitening products, only use one your doctor recommends.

6. Cracked teeth

Cracked teeth are another cause of tooth sensitivity you should beware of.  If you have chipped or broken teeth, your gums become more venerable to bacteria which can travel down to the tooth dentin and cause sensitivity and toothache.
