What should a dental hygienist do if a sealant is partially missing after placement?

The best course of action for a dental hygienist in the event that a sealant is partially missing is to assess the need for replacement and possibly reapply the sealant. This approach emphasizes the importance of evaluating the condition of the tooth and the sealant itself before proceeding with any further treatment.

Conducting an assessment allows the hygienist to determine whether the remaining sealant is still effective and if there are any signs of decay or damage to the tooth underneath. If the sealant is no longer serving its protective purpose, or if there are concerns about the health of the tooth, reapplying the sealant can help maintain the integrity of the tooth and prevent further decay.

By focusing on the assessment rather than immediate reapplication or disregard for the issue, the hygienist ensures that they are providing the best care possible, taking into account the actual situation of the tooth rather than following a one-size-fits-all approach. This allows for informed decision-making based on the specific needs of each patient.
