Does teeth cleaning affect cracked teeth?


Hello, six months ago, I had a diagonal crack in a lower molar that underwent root canal treatment and was filled with resin.
I would like to know if getting a dental cleaning will have any impact on the cracked tooth.
(The tooth has yellow-brown discoloration, and the gums are slightly swollen and painful).
Thank you for your response.

Hello: It is recommended to inform the dentist before the teeth cleaning that the area has a history of tooth fracture, so please proceed with caution or use special instruments for cleaning.
Alternatively, you may return to the original endodontist who performed the root canal treatment for further management.

When it comes to dental health, especially regarding cracked teeth, it is essential to understand the implications of teeth cleaning and how it may affect your existing dental issues. In your case, you mentioned that you have a cracked lower molar that has undergone root canal treatment and resin filling. You are now considering a dental cleaning, but you are concerned about the potential impact on your cracked tooth.

First and foremost, professional teeth cleaning, also known as dental prophylaxis, is generally safe for teeth that have been treated for cracks or other issues, provided that the cleaning is performed by a qualified dental professional. The cleaning process typically involves the removal of plaque and tartar buildup using specialized tools, which can help improve gum health and overall oral hygiene. In your case, since you have yellow-brown discoloration and slight gum swelling, a cleaning could be beneficial in reducing bacteria and preventing further gum disease.

However, there are a few considerations to keep in mind:
1. Condition of the Cracked Tooth: Since your molar has already been treated with a root canal and filled with resin, it is crucial to ensure that the integrity of the filling is maintained. If the crack is extensive or if there are signs of infection or further damage, it may be wise to consult your dentist before proceeding with a cleaning. They can assess whether the tooth is stable enough for cleaning without risking further damage.

2. Technique Used: The method of cleaning can also influence the outcome. Ultrasonic scalers, which use vibrations to remove plaque, may be less invasive than manual scaling, but they can still cause discomfort if the tooth is sensitive. Make sure to inform your dental hygienist about your cracked tooth so they can adjust their technique accordingly.

3. Post-Cleaning Care: After a cleaning, it is common for gums to be slightly tender, especially if there was significant tartar buildup. You should follow up with good oral hygiene practices, including gentle brushing and the use of an antibacterial mouthwash, to help soothe your gums and prevent further irritation.

4. Monitoring Symptoms: After your cleaning, keep an eye on any changes in your cracked tooth or surrounding gums. If you experience increased pain, swelling, or any other concerning symptoms, contact your dentist immediately. They may need to evaluate the tooth to ensure that the cleaning did not exacerbate any underlying issues.

5. Regular Dental Visits: Regular dental check-ups are crucial, especially for teeth that have undergone significant treatment. Your dentist can monitor the condition of your cracked tooth and ensure that it remains healthy over time.

In conclusion, while teeth cleaning can be beneficial for your overall oral health, it is essential to communicate with your dental professional about your specific concerns regarding your cracked tooth. They can provide personalized advice and ensure that the cleaning process is safe and effective for your situation. Remember, maintaining good oral hygiene and addressing any dental issues promptly can help prevent further complications and preserve your dental health.
