Question 1

Can Duraphat cause mouth ulcers?

Accepted Answer

Mouth ulcers are not a listed side effect. However, sodium laurilsulfate in toothpaste can irritate sensitive mouths. If ulcers persist, consult your dentist.

What should I do if I experience an allergic reaction?

Accepted Answer

Stop using Duraphat immediately. If symptoms are mild (rash, itching), contact your pharmacist or GP. If you have swelling of face/lips or difficulty breathing, seek emergency care.

Question 3

Is it safe to use Duraphat if I have kidney disease?

Limited data in pregnancy; use only if recommended by a dentist and ensure you spit out thoroughly. In breastfeeding, it's considered safe with correct use.
