After dental root canal surgery is done, it is enough to satisfy light, nutritious and soft in diet, such as spinach, banana, fish and lean meat. 1. Diet after root canal treatment should be light, nutritious and soft. For vegetables, you can eat more spinach, oleander, cucumber, winter melon, etc.; for fruits, you can eat banana, kiwi, strawberries, blueberries, durian, etc.; for meat, you can eat more beef, chicken, fish, etc.. These foods are better digested and softer, and are less likely to wear down the teeth during eating. 2. After root canal treatment, you can only follow a light diet and try not to add pepper, chili, peppercorns, ginger, scallions, etc. These are harsh seasonings. These are irritating condiments, which are easy to stimulate the gum tissue when eating at the beginning, and are not conducive to the recovery of root canal treatment. Dental root canal treatment should be regularly reviewed, and then adjust the treatment plan at any time, if there is any doubt about the diet, you should consult your doctor.
