A whiter smile can enhance your confidence, but stains on teeth can make them look dull. Crest Whitening Strips are a popular and convenient solution for removing discoloration. But do they work on all types of stains? Understanding how these strips interact with different kinds of stains can help you set realistic expectations.
Tooth stains fall into two main categories—extrinsic (surface stains) and intrinsic (deep stains). Crest Whitening Strips work differently depending on the type of discoloration.
Extrinsic stains appear on the outer layer of the teeth (enamel) and are caused by:
Drinking coffee, tea, or red wine
Smoking or tobacco use
Eating dark-colored foods like berries and soy sauce
Effectiveness of Crest Whitening Strips:
Crest Whitening Strips use an enamel-safe whitening agent that helps lift surface stains. These strips penetrate the enamel to break down stain molecules, revealing a whiter appearance. With consistent use, surface stains can fade significantly.
Intrinsic stains develop inside the tooth and are caused by:
Natural aging (yellowing of teeth over time)
Certain medications (e.g., tetracycline)
Excessive fluoride exposure in childhood
Effectiveness of Crest Whitening Strips:
While these strips can help lighten mild intrinsic stains, they may not completely remove deep discoloration. More stubborn stains may require professional whitening treatments. However, regular use of Crest Whitening Strips can still improve overall brightness.
