Avoid eating nuts, spicy foods, and seeds 24 hours after visiting the dentist. You can eat soft foods.
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.
Great question. Without knowing what you had performed, I will try my best to answer.
If you had a cleaning and fluoride treatment, eating or drinking with 30 minutes won't give the fluoride time to break the matrix and exchange with the calcium in your teeth; fluoride helps make your teeth cavity-resistant.
If you had a crown preparation, if you had shouldn't eat anything sticky to displace the "temporary" restoration. This restoration helps to protect the tooth from sensation (the enamel layer was stripped away and the layer left contains the nerve, which is more open to stimuli,) protect the integrity of the work performed, helps the appearance of the tooth and keeps the tooth from shifting while you're waiting on your crown (if the tooth shifts, the crown may not fit, even after adjustments, and the procedure will have to be repeated.) If your temporary becomes displaced, report to your dentist immediately to have it replaced. If this isn't possible, your local pharmacy should carry dental temporary material until you can return.
If you were numbed, or had to take an injection for any reason, while eating, you may not be able to feel your tongue or lips and may mistakenly bite them. This is especially true for children.
Lastly, if you had an extraction, the most important thing is that the extraction needs to form a clot. A clot walls off the area to promote healing similar to a scab on your knee. Spicy foods can raise your blood pressure to disrupt a clot. Citrus acid and carbonated drinks can wash it away, as does hydrogen peroxide, salt water and mouthwash. Hot foods, such
as soup, and crunchy foods can irritate the site. Bottom line, if the clot is washed away, a "dry socket" can form; these are more uncomfortable than a toothache! Should this happen, go back to the treating dentist immediately.
Hope this helps. Good luck!
First of all, I hope the procedure went well for you. If it was a filling, the only reason we recommend waiting to eat is due to the numbness. We don’t want you biting or burning your lip/cheek/tongue. You are more than welcome to eat soft foods immediately after a filling/crown/root canal, but we do recommend eating on the opposite side that you are numb.
If it was an extraction, we recommend the same timeline for numbness to go away, but I recommend eating on the opposite side of the extraction for 24 hours to give the trauma site initial time to begin healing. For extractions, try to avoid smoking, drinking through a straw, spitting, and blowing your nose hard for 48-72 hours to minimize the chance of dry socket.
