Don’t Brush Your Teeth After Vomiting

Reflux and vomiting are common in people of all ages.

Many people are surprised to learn that they shouldn’t brush their teeth straight after having reflux or vomiting.

The reason behind this is that the acid from the stomach softens the outer layer of the teeth, leaving it vulnerable to being brushed away with a toothbrush.

Repeated brushing after reflux or vomiting results in loss of tooth structure that cannot be replaced by the body.


  • Rinse your mouth with water, and wait 30 minutes before brushing your teeth, as the acid from your stomach will soften your teeth enamel.
  • Allow your saliva 30 minutes to harden your enamel before brushing will prevent you brushing off that microscopic soft upper layer.
  • Use a fluoride toothpaste when brushing to maximise the uptake of minerals from your saliva back into the tooth.
  • Avoid acidic drinks and foods during periods of frequent reflux and vomiting. These will only increase the amount of tooth structure that is lost.

Remember to keep your dental team informed of any health conditions, including reflux and regular vomiting so that we can assist you to prevent dental disease caused by these conditions.
