Rinsing and Brushing Teeth with Salt: Three Factors to Consider in Your Oral Care

Alternative dental products containing natural ingredients, such as salt, have been a trend in recent years – and it's no surprise why. From adding flavour to food to providing important health benefits, salt has many advantages, including improving your dental health.

If you're considering adding salt to your oral care routine, keep these three factors in mind to do it safely – and to enjoy a more natural lifestyle!

1. Saltwater Rinses

Rinsing your mouth with saltwater is beneficial in many situations, including:

  • After tooth extractions: A study in Evidence-Based Dentistry, published on behalf of the British Dental Association, found that using a warm saline mouthwash at least twice daily significantly reduces the occurrence of dry socket – the persistent, throbbing pain and exposure of the bare alveolar bone (which contains the tooth sockets) that usually occurs within 48 to 72 hours of a tooth extraction.
  • Oral thrush: The United States Mayo Clinic recommends using a warm saltwater rinse during an oral thrush outbreak.
  • Canker sores: By removing some germs and decreasing tenderness, salt rinses can help relieve canker sore pain.

2. Brushing Teeth with Salt

Salt toothpaste has become more popular, but how effective is it? And does it improve your dental health? A study in the open-access journal Oral Health and Preventive Dentistry found that the addition of sea salt to traditional abrasives in toothpaste can cause highly abrasive dentin wear – without providing any additional dental benefits. Consult a dentist if you still want to use natural toothpaste.

Going the DIY route and using salt directly on your teeth to eliminate stains is also highly inadvisable, as salt's abrasive nature could cause permanent damage to them.

3. Salt is Not a Replacement for Fluoride

If you’re looking to incorporate salt as an ingredient in your toothpaste, ensure that fluoride is still in the mix, as per the South African Dental Association's recommendation. This naturally occurring mineral helps prevent cavities in adults and children by making the teeth's outer surface more resistant to acid attacks. Your dentist can help guide you here as well!

Salt is a versatile ingredient with many benefits – so don't hesitate to consult with your dentist while exploring natural solutions for your teeth. Together, you can brainstorm to keep them healthy and bright for years to come!
