Sensitivity after dental cleaning?


I would like to ask Dr.
Ting-Fang, after having my teeth cleaned last week, I noticed that my teeth became a bit sensitive to cold and hot drinks the next day, but I didn't experience this sensitivity before the cleaning.
Could this be caused by small cavities?

Dr. Huang Tingfang reply Dentistry


Dear Ms.
Li,
Hello! It is normal to experience tooth sensitivity after a dental cleaning.
To check for any small cavities, an X-ray can provide that information.
Take care! Wishing you all the best and smooth sailing!
Sincerely,
Dr.

More Info


Post-teeth cleaning sensitivity is a common concern among patients, and it can be attributed to several factors. After a professional dental cleaning, many individuals experience heightened sensitivity to hot and cold temperatures, which can be alarming, especially if they have not experienced such sensitivity before.
One of the primary reasons for this sensitivity is the removal of plaque and tartar that may have been protecting the tooth surfaces. When these deposits are cleaned away, the underlying dentin, which is more sensitive than enamel, may become exposed. This exposure can lead to discomfort when consuming hot or cold foods and beverages. In your case, since you mentioned that you did not experience sensitivity before the cleaning, it is likely that the cleaning process has revealed areas of your teeth that were previously shielded by plaque or calculus.

Additionally, if you had small cavities (caries) before the cleaning, these could also contribute to sensitivity. Cavities can weaken the tooth structure and make it more susceptible to temperature changes. If the sensitivity persists, it would be wise to consult your dentist to evaluate whether these small cavities need treatment or if there are other underlying issues contributing to your discomfort.

In terms of solutions, there are several strategies you can employ to manage post-cleaning sensitivity:
1. Desensitizing Toothpaste: Using a toothpaste specifically designed for sensitive teeth can help. These products contain compounds that block the transmission of sensation from the tooth surface to the nerve.

2. Avoiding Extreme Temperatures: For the time being, try to avoid very hot or cold foods and drinks. This can help minimize discomfort while your teeth adjust after the cleaning.

3. Fluoride Treatments: Your dentist may recommend a fluoride treatment to strengthen the enamel and reduce sensitivity. This can be particularly helpful if the sensitivity is due to exposed dentin.

4. Good Oral Hygiene: Maintaining a rigorous oral hygiene routine can prevent further plaque buildup and protect your teeth from sensitivity. This includes brushing twice daily with a soft-bristled toothbrush and flossing regularly.

5. Regular Dental Check-ups: Regular visits to your dentist for cleanings and check-ups can help catch any potential issues early, including cavities that may lead to sensitivity.

If your sensitivity continues for more than a few weeks or worsens, it is essential to return to your dentist for a thorough examination. They may need to take X-rays to check for any underlying issues, such as deep cavities or gum disease, that could be contributing to your sensitivity.

In summary, while post-teeth cleaning sensitivity can be a normal reaction, it is crucial to monitor the situation. If you suspect that small cavities are the cause, addressing them promptly with your dentist will help prevent further discomfort and maintain your oral health.
