Dental · FAQ
What side effects can prescription dental rinses, gels, and troches cause?
Short answer
Side effects depend on the ingredients. Dental products may cause irritation, taste changes, staining, or numbness. Pilocarpine can cause sweating and other whole-body effects. Ask about your exact formula before starting. Stop use and seek emergency help for trouble breathing or swelling of the lips, tongue, or throat.
Each dental treatment has its own risks. Chlorhexidine can cause tooth or tongue staining, taste changes, and mouth irritation. Dry mouth rinses and custom antimicrobial products may also irritate tissue or trigger an allergy. High-fluoride rinse should not be swallowed; swallowing too much can be harmful, especially for children.
Lidocaine can numb the mouth and throat, which may raise the risk of biting yourself or having trouble swallowing. Too much lidocaine can cause serious harm. Diphenhydramine may cause sleepiness, especially if swallowed. Pilocarpine can cause sweating, nausea, dizziness, and changes in heart rate. These are examples, not a complete list of possible side effects.
Ask the dentist or pharmacist to review the exact ingredients and safety instructions for your prescription. Use only the prescribed amount, and keep it away from children and pets. Contact your dentist about new or bothersome symptoms. Call 911 for trouble breathing, severe swelling, fainting, or a seizure. For accidental swallowing or a possible overdose, contact Poison Control at 1-800-222-1222.
