In adults, generally, as we age, we tend to lose bone density, especially around the front teeth, so the roots of the teeth feel the temperature changes more. Also, gum recession causes more root exposure, be mindful that roots don’t have the enamel layer which is the protective shield for the coronal portion of the tooth. Roots of the teeth are more sensitive to heat and cold. Several things can cause gum recession:
-Grinding your teeth
-Restorations that are too close to the bone level
You need to have a clinical exam to determine what is the reason for your teeth sensitivity and receive the proper treatment.
Cleaning (regular and deep): if the mouth was irrigated with antibiotic rinse or fluoride application was applied, we ask the patient not to eat for 30 minutes.
For kids, if any work was done on the lower teeth because of numbness of the tongue, they tend to bite their cheeks and tongue, so no eating till the numbness goes away.
For surgeries, nothing too hot as it can induce bleeding. Also, for faster recovery, avoid sweets as bacteria thrive on sugary foods and your immune system instead of healing the surgical site, fights the bacteria.
If you had a crown preparation, avoid hard and crunchy food till you receive the final restoration (crown) as your tooth without the crown is fragile, and temporary crown is not as strong as the crown is.
For composites (white fillings), avoid the foods that have red colors and alcoholic beverages and generally the things that can stain your teeth for 2 days, the same thing applies for in office teeth-whitening procedure. For that one, you need to avoid coffee and tea as well for at least 7 days.
After crown delivery, avoid sticky foods for 2 days.
