Fluoride Treatment: A Post Care Guide to Eating & Drinking

Whether you or your child is getting a fluoride treatment, you may have a ton of questions about the outcome, such as;

How long should I wait to drink after fluoride treatment?

Will fluoride treatment prevent cavities for life?

At Dastrup Dental, we respond to these questions all the time. 

So, if you haven’t received answers to most of your questions, read closely.

This article responds to common questions about fluoride treatment post-care.

How much does a fluoride treatment cost?

The cost of fluoride treatment is usually between $10 to $30. Most times, insurance covers the cost of a fluoride treatment for children, while adults may have to pay out of pocket. 

Always speak with your dentist about your payment options before proceeding with the treatment.

How long should I wait to drink after fluoride treatment?

Fluoride treatments have a higher concentration of fluoride than the average concentration in your regular toothpaste. As a result, there are specific post-care guides to follow after a fluoride treatment.

Generally, patients are advised to wait for 6 hours before taking any hot liquid, alcohol, or using mouthwash. 

However, you can consume cold drinks minutes after a fluoride treatment.

How long until you can eat after fluoride treatment?

The same precautions for drinking liquid applies to eating after fluoride treatment. You should avoid eating food for at least 6 hours after a fluoride treatment. 

If you must, then eat soft foods – greek yoghurt, mashed potatoes, scrambled eggs, ice cream, mashed bananas, and blended soups. 

Soft foods won’t reduce the effectiveness of the fluoride treatment, unlike hard food. 

The primary difference between soft and hard food is texture. Soft foods are easy to eat while hard foods are hard to chew, e.g. popcorn and candy.

Keep these differences in mind when choosing your diet for the first 6 hours after a fluoride treatment.

What can I eat after fluoride treatment?

As stated earlier, soft foods are the best type of food during the first 6 hours of a fluoride treatment. 

That said, you can eat any of the following soft foods;

  • Mashed potatoes
  • Porridge oats
  • Crème Fraiche
  • Cheese sauce
  • Whole grain biscuits with milk
  • Boiled pasta or rice with sauce
  • Minced meat
  • Yogurt
  • Cottage cheese
  • White or brown bread

When can I brush my teeth after fluoride treatment?

Wait between 4 – 6 hours before resuming your routine oral care. To stay on the side of caution, you should wait for 6 hours before brushing or flossing your teeth. 

When you wait for 6 hours or longer, the fluoride will cover and protect your teeth better.


Fluoride treatment is a proven way to protect and strengthen the dentition from cavities. Dentists provide fluoride treatments in the form of a concentrated gel, varnish, rinse, foam or spray. 

In Davidson, North Carolina, and most of the US, fluoride is added to the local water supply to improve the dentition of residents

The concentration of fluoride added to local water is considered safe for use. For personal treatments, fluoride should be applied by your dentist to ensure safe use. When used in high concentrations, fluoride can become a health risk
