Less Common but Important Side Effects
- Allergic Reactions: If you have sensitive skin or allergies, watch out for signs like itching, swelling, or rash. I recommend doing a patch test or consulting a healthcare professional if you’re unsure.
- Staining of Teeth: Although rare, some users have reported slight staining with long-term use. I made sure to maintain regular dental cleanings to prevent this.
Who Should Be Cautious?
If you have certain conditions such as sensitive gums, oral ulcers, or allergies to mouthwash ingredients, it’s best to speak with your dentist before using Smart Mouth. I found that discussing with my dentist gave me peace of mind.
Tips to Minimize Side Effects
