I sometimes have pain in one tooth (especially when exposed to cold) and aside from Sensodyne toothpaste, what else can I use as a product?

In addition to Sensodyne toothpaste, you can also use other products specifically designed for sensitive teeth. Some options include toothpastes with fluoride, desensitizing toothpaste, or mouthwash for sensitive teeth. You may also consider using a soft-bristled toothbrush and avoiding acidic foods and drinks that can worsen sensitivity. If the pain persists, it's important to follow up with your dentist for further evaluation and treatment options.
