The 26 Most Frequently Asked Questions About Teeth Whitening

1. What is teeth whitening and how does it work?
   Teeth whitening is a cosmetic dental treatment designed to lighten the color of teeth. It works by applying whitening agents (such as hydrogen peroxide or carbamide peroxide), which penetrate the enamel and break down the molecules that cause yellowish tones, resulting in a brighter smile.
2. Does teeth whitening damage the enamel or is it safe for my teeth?
   No, treatments performed by professionals are safe and do not damage the enamel when properly done in the dental office, following the manufacturer’s instructions and using high-quality materials.
3. How long does the effect of teeth whitening last?
   It depends. Results typically last between 6 months and 2 years, depending on the patient’s habits and the type of treatment chosen.
4. Does teeth whitening cause sensitivity?
   Sometimes, it can cause temporary sensitivity during the treatment, but it is transient and manageable. In our office, we use materials that do not require light (heat) activation, providing comfort and reducing the likelihood of sensitivity.
5. What is the difference between in-office and at-home teeth whitening?
   In-office whitening is performed in the dental chair and is more potent and faster due to a higher concentration of peroxide. At-home whitening is done using custom-made trays under professional supervision, with gradual improvement in results.
6. What is combined whitening?
   This involves in-office whitening sessions followed by at-home whitening with custom trays, enhancing results and maintaining the achieved brightness for a longer period.
7. How many sessions are needed to see results?
   In-office treatments usually require 1-3 sessions on different days to manage sensitivity and optimize results. At-home whitening typically lasts 2-3 weeks, depending on patient compliance.
8. Is the teeth whitening procedure painful?
   No, the procedure itself is not painful, although some temporary sensitivity may occur due to enamel defects such as wear, fractures, or dental abfractions.
9. Can all teeth be whitened?
   Yes, but not all teeth respond equally. Stains caused by tetracyclines or fluorosis may be more resistant and may require alternative treatments.
10. Can I whiten my teeth if I have fillings, crowns, or veneers?
    Materials like resin or ceramic veneers do not whiten, so if you have resin fillings, crowns, or a smile design, you may need to replace them.
11. How much does professional teeth whitening cost?
    Prices vary depending on the type of whitening chosen. In our office, treatments range from $400,000 COP (98 USD) to $900,000 COP (220 USD). Investing in oral health is crucial, and choosing cheap alternatives can lead to poor or painful results.
12. Is it safe to get whitening if I have cavities or periodontal disease?
    No. Cavities and periodontal disease should be treated before whitening to avoid complications. Prioritizing oral health ensures a healthy and beautiful smile.
13. What foods should I avoid during and after whitening?
    Avoid foods and beverages that stain teeth, such as coffee, red wine, tea, sodas, alcoholic or acidic drinks, curry, beets, carrots, processed snacks like Doritos, and very hot or cold beverages.
14. At what age can someone get teeth whitening?
    Whitening is generally recommended for individuals over 18 years old, but each case should be evaluated. Some patients with brown stains from fluorosis or tetracycline may require specialized treatment before whitening.
15. Does whitening work on yellow teeth?
    Yes, whitening is most effective on naturally yellow teeth caused by intrinsic or extrinsic factors.
16. Can I whiten my teeth if I am pregnant or breastfeeding?
    No. It is best to avoid cosmetic procedures during pregnancy or breastfeeding to prevent unnecessary exposure to whitening agents.
17. How long should I wait between whitening sessions?
    In-office sessions are typically spaced every other day to maximize results and minimize sensitivity. At-home whitening should be used daily according to the recommended hours and concentration.
18. Are over-the-counter whitening products effective?
    They are less effective than professional treatments and can be risky if misused, potentially damaging enamel or increasing sensitivity.
19. Are there risks in teeth whitening?
    The main risks are temporary sensitivity and gum irritation, which can be minimized by having the procedure performed by a specialist.
20. How white can my teeth get?
    Results depend on original tooth color, stain type, and individual response to treatment. While exact shades cannot be guaranteed, whitening significantly improves tooth color.
21. Can I exercise during the whitening treatment?
    Yes, you can maintain normal activities.
22. Does whitening affect the gums?
    No, although peroxide can cause temporary irritation if it contacts the gums, which is why professional application is crucial.
23. How can I maintain my whitening results?
    Brush at least three times a day, use dental floss, attend regular check-ups, and schedule touch-ups as needed.
24. Is teeth whitening addictive?
    No, but some patients become overly concerned with keeping their teeth white. Regular check-ups help ensure maintenance without unnecessary procedures.
25. Can I whiten my teeth if I have braces?
    No, it is best to wait until after orthodontic treatment is complete and tissues have stabilized.
26. What if I have an emergency during at-home whitening?
    You can contact me anytime for guidance.
27. Is teeth whitening permanent?
    No, but with proper care and maintenance, results can last a long time.

Additional Common Questions:

1. What is the difference between professional whitening and store-bought kits?
   Professional whitening guarantees faster, safer, and more effective results with high-quality whitening agents and advanced technology. Store-bought kits have lower concentrations and may not be as effective, potentially leading to uneven results or enamel damage.
2. Does whitening work on coffee or tobacco stains?
   Yes, but deep stains may require a professional cleaning before whitening for optimal results.
3. Are natural whitening methods like activated charcoal effective?
   No scientific evidence supports their safety or effectiveness. Charcoal may remove surface stains but does not penetrate enamel or break down internal stains. It can also be abrasive, wearing down enamel and increasing sensitivity.
4. How do I know if I am a good candidate for whitening?
   A consultation is necessary to assess oral health. Ideal candidates have stains from food, beverages, or aging, and healthy teeth and gums without cavities or periodontal disease. Whitening does not work on crowns, veneers, or visible fillings.
