After obtaining a filling, you could assume that you shouldn't brush your teeth for at least a few days, which is untrue. In reality, brushing your teeth usually after getting a tooth repaired is quite acceptable, and you are even advised and be careful not to brush too vigorously as this can irritate the filling and your teeth, which can result in tooth discomfort and further cavities. It's crucial to brush your teeth to avoid developing cavities from consuming sugary meals.
