Are sealants the only preventative measure used?

  1. Yes

  2. No

  3. Sometimes

  4. Only in adults

The correct answer is: No

The option "No" is the most accurate answer because while sealants are one effective preventative measure used for protecting teeth against decay, there are other preventative measures that can be used in addition to or instead of sealants. For example, proper oral hygiene habits such as brushing and flossing regularly, eating a balanced and nutritious diet, and visiting the dentist for regular check-ups and cleanings are also important preventative measures. Therefore, it would be incorrect to say that sealants are the only preventative measure used.
