Orthodontic crown lengthening procedure


Eight years ago, I underwent crown lengthening surgery before getting a dental crown.
Recently, my crown has been damaged and needs to be replaced.
After removing the old crown, the silver filling from the crown lengthening procedure done years ago was also removed by the dentist, and a temporary crown was placed.
I would like to ask: 1.
Will I need to undergo crown lengthening surgery again? 2.
The temporary crown feels ill-fitting; what should I do about that?

Dear Ms.
Anonymous: Hello! (Orthodontic crown lengthening procedure) is necessary when the decay is too deep, exposing the tooth root.
If there is further decay, we need to assess whether the tooth root is long enough.
Please communicate more with your dentist! Thank you! Wishing you safety! Sincerely, Dr.
Huang Ting-Fang, Dentistry.

More Info


Crown lengthening is a dental procedure that involves reshaping the gum tissue and, in some cases, the underlying bone to expose more of a tooth's structure. This procedure is often performed when a tooth is decayed or fractured below the gum line, making it difficult to place a crown. It can also be done for aesthetic reasons, to create a more balanced smile. In your case, since you had crown lengthening done eight years ago, it is essential to consider whether the current condition of your tooth and surrounding tissue necessitates repeating the procedure.

1. Do you need to undergo crown lengthening again?
Whether you need to repeat the crown lengthening procedure depends on several factors. If the previous crown lengthening has provided sufficient tooth structure for the new crown, and there are no issues with the gum tissue or bone that would require further exposure of the tooth, then it may not be necessary. However, if the new crown requires more tooth structure to be adequately supported, or if the gum tissue has receded since the last procedure, your dentist may recommend crown lengthening again. It’s crucial to have a thorough examination and discussion with your dentist about the condition of your tooth and the surrounding tissues to make an informed decision.

2. What to do if the temporary crown feels ill-fitting?
Temporary crowns are designed to protect the tooth while the permanent crown is being fabricated. However, they can sometimes feel uncomfortable or ill-fitting. If your temporary crown feels loose, tight, or causes discomfort, it’s essential to contact your dentist. They can adjust the temporary crown to ensure it fits properly and does not cause any irritation to your gums or adjacent teeth. It’s important to address any discomfort promptly, as an ill-fitting temporary crown can lead to further complications, such as gum irritation or tooth sensitivity.

In the meantime, here are some tips for managing your temporary crown:
- Avoid sticky or hard foods: These can dislodge the temporary crown or cause it to break.

- Maintain good oral hygiene: Brush gently around the temporary crown and floss carefully to avoid dislodging it.

- Use dental wax: If the edges of the temporary crown are sharp or irritating your gums, dental wax can provide a protective barrier.

In conclusion, whether you need to repeat crown lengthening depends on the current condition of your tooth and the requirements for the new crown. If the temporary crown feels uncomfortable, it’s crucial to communicate with your dentist for adjustments. Regular follow-ups and open communication with your dental care provider will ensure that you receive the best possible care and outcomes for your dental restoration.
