Final answer:
The exception to the treatments that occlude dentinal tubules and thus reduce tooth sensitivity is dental veneers, as they are meant for cosmetic enhancement rather than for treating sensitivity.
Step-by-step explanation:
Dental Treatments for Sensitivity
When a client reports extreme sensitivity in the lower anterior teeth, there are several treatments that can occlude the dentinal tubules to alleviate this discomfort. One of the options includes using desensitizing toothpaste, often containing active ingredients such as strontium chloride or potassium nitrate, which help reduce tooth sensitivity. Clinical trials have shown that toothpastes containing arginine and calcium sodium phosphosilicate (CSPS) can also be effective. Dental procedures that occlude dentinal tubules include dental sealants, dental bonding, and dental crowns. Dental sealants and bonding involve applying a protective plastic or resin material to the tooth surface, while dental crowns are caps placed over the entire tooth. Dental veneers, which are thin shells of porcelain or composite material bonded to the front of teeth, are the exception, as they are primarily cosmetic and do not serve the purpose of occluding dentinal tubules to reduce sensitivity.
