Frequently Asked Question
1. How do I care for my teeth while wearing braces?
Brush thoroughly after every meal using a soft-bristled toothbrush with fluoride toothpaste. Clean around brackets and wires carefully. Use floss threaders, orthodontic floss, or water flossers to clean between teeth where regular flossing is difficult.
2. Will braces interfere with daily activities like sports or playing musical instruments?
Braces shouldn't prevent you from enjoying sports or musical instruments. For contact sports, Dr. Sharma recommends wearing a braces-specific mouthguard to protect both your teeth and orthodontic appliances from potential injury.
3. What foods should I avoid while wearing braces?
Avoid sticky foods (gum, caramel), hard items (nuts, ice), and crunchy snacks (popcorn, chips) as these can damage braces. Cut raw fruits and vegetables into smaller pieces to prevent breaking brackets or bending wires.
4. Is orthodontic treatment painful?
Some discomfort is normal after initial placement and adjustments, typically lasting a few days. Manage soreness with soft foods and over-the-counter pain relievers. This temporary discomfort indicates your teeth are shifting properly.
5. What happens after braces are removed?
After removal, you'll enter the retention phase with custom retainers. These maintain your new alignment by preventing teeth from shifting back. Initially worn full-time, most patients transition to nighttime wear as directed by your orthodontist.
6. Can adults get orthodontic treatment?
Yes! Adults of any age can benefit from orthodontic care. Treatment plans are customized to address specific needs, lifestyle, and goals. Options include traditional braces or clear aligners like Invisalign.
7. What if I have missing teeth or gum disease?
These conditions don't automatically disqualify you from treatment. Your orthodontist will work with your dentist or periodontist on a comprehensive plan, potentially treating gum issues first or planning for future tooth replacements.
8. Will wisdom teeth affect my orthodontic treatment?
While wisdom teeth don't necessarily cause crowding after orthodontic treatment, your orthodontist might recommend removal based on your specific dental situation to ensure long-term stability and health.
