People with sensitive teeth often wonder whether mouthwashes help in addition to toothpastes for sensitive teeth. Mouthwashes for sensitivity can play a supporting role, but they are not a solution on their own, and finding the cause of the sensitivity is important.
How do sensitivity mouthwashes work?
- Ingredients that reduce nerve stimulation: Substances such as potassium nitrate can help reduce stimulation of the nerve endings inside the tooth.
- Ingredients that seal the tubules: Some ingredients help block the open tubules on the dentin surface.
- Fluoride: Strengthens the enamel and helps protect against decay.
What to look for when choosing a mouthwash
- Choose products stated to be for sensitivity.
- Alcohol-free mouthwashes may be more comfortable in terms of dry mouth and burning.
- Ask your dentist or pharmacist when choosing products for long-term use.
- In children, mouthwash should be used in an age-appropriate way and under parental supervision because of the risk of swallowing.
Correct use
- Use the amount and time recommended by the product; it is usually used once or twice a day.
- Use mouthwash in addition to brushing, not instead of it.
- Not eating or drinking for a while after rinsing may increase the effect; follow the product's instructions.
- The effect may take a few weeks of regular use to appear.
Toothpaste or mouthwash?
Toothpastes developed for sensitive teeth are generally the first choice for reducing sensitivity with regular use. Mouthwashes can support this effect. For details, see our article on choosing a toothpaste for sensitive teeth.
See your dentist
Sensitivity may be due to a cause that needs treatment, such as decay, a cracked tooth, gum recession or a failing old filling. If sensitivity continues despite using mouthwash and toothpaste, or is concentrated in one particular tooth, an examination is needed. Fluoride varnish, desensitising agents or bonding applied in the clinic may give faster relief.
Regular check-ups
Check-ups every six months allow problems that can cause sensitivity to be spotted early.
