Let’s talk about mouthwash and its effect on teeth.
Many dentists recommend that people with chronic cases of oral problems use mouthwash twice daily. It’s best used after brushing, and spit out after swishing vigorously. (Never swallow it).
Using too often can cause fluorosis, which results in obvious white spots developing due to over-application of fluoride. Any allergic reaction to mouthwashes or rinses is rare. Symptoms of serious allergic reaction include rash, itching/swelling (especially of the face/tongue/throat), severe dizziness and trouble breathing.
Before using medicated mouthwashes, share your medical history with your dentist or pharmacist, especially with mouth problems, such as mucositis or mouth sores. Also inform them of all prescribed and non-prescribed/herbal products, especially other fluoride preparations.
Using mouthwash does NOT replace good dental habits. Continue to brush and floss your teeth regularly as directed by your dentist, and have regular dental checkups.
