You can eat ice cream the next day after washing your teeth, but it depends on your personal situation. If the teeth are not sour and insensitive the next day after cleaning, you can eat ice cream properly. If you have pain or sensitivity, it may be dentine hypersensitivity. You need to extend the time and wait for your teeth to return to normal before eating ice cream.

Generally, you can't eat cold, sour or sweet food after tooth cleaning, because these foods will cause irritation to enamel and aggravate local pain and swelling. It is suggested to choose a more formal medical institution and find an experienced doctor for surgery, which can reduce local injuries. At the same time, attention should be paid to oral care after tooth washing to keep the oral cavity clean and hygienic, which is helpful to oral health.

The above information is for reference only. If you have any questions about oral health, it is recommended to consult a professional doctor.
