Ace the NBDHE Dental Hygienist Test 2026 – Sparkling Success Awaits!

Extrinsic stains on teeth are specifically those that originate from external sources, such as food, beverages, tobacco, and poor oral hygiene. One of the defining characteristics of these types of stains is that they reside on the external surface of the tooth enamel and do not penetrate the tooth structure itself. Because of this, they can be effectively removed through professional cleaning methods, such as scaling or polishing performed by a dental hygienist.

These stains are not influenced by internal factors, nor do they require invasive procedures like surgery to remove, making the understanding of their treatment crucial for dental professionals. Their removability is a significant aspect to emphasize regarding extrinsic stains and highlights the importance of regular dental cleanings to maintain oral health and aesthetics.
