How to Whiten Back Teeth? (Reddit)

Let’s cut to the chase: whitening back teeth presents a unique challenge compared to front teeth, primarily due to accessibility. The Reddit hive mind often buzzes with DIY solutions, but professional guidance is crucial. Effective methods include professional in-office whitening treatments, like laser whitening or power bleaching, which reach even the molars. Custom-fitted whitening trays with professional-grade gel, prescribed by your dentist, can also work, though it might be harder to ensure complete coverage in the back. Over-the-counter whitening strips and toothpastes offer limited results and may not reach the back teeth effectively. Ultimately, a consultation with your dentist is essential to determine the best and safest approach tailored to your individual needs and dental health.

Understanding the Challenges of Whitening Molars

Whitening your back teeth isn’t as simple as slapping on a whitening strip. Several factors complicate the process, and ignoring them can lead to disappointment or even harm.

Accessibility Issues

The most obvious challenge is simply reaching those back teeth! It’s harder to apply whitening agents evenly and effectively in the molar region, whether you’re using strips, trays, or even just brushing with whitening toothpaste.

Uneven Whitening Concerns

Because of the accessibility issues, it’s common to experience uneven whitening. The front teeth might become noticeably brighter, leaving the back teeth looking dull in comparison. This can create an unnatural and undesirable result.

Enamel Thickness Varies

The thickness of enamel can vary across different teeth and even within the same tooth. Back teeth, especially molars, might have areas with thinner enamel, making them more susceptible to sensitivity during whitening.

Professional Whitening: The Gold Standard

When it comes to whitening back teeth effectively and safely, professional treatments are generally the most reliable option.

In-Office Power Whitening

In-office whitening, often referred to as power bleaching or laser whitening, involves a dentist applying a high concentration of hydrogen peroxide or carbamide peroxide gel to the teeth. A special light or laser might be used to activate the gel and accelerate the whitening process. This method offers several advantages:

• Strongest Whitening: Delivers the most dramatic results in a single visit.
• Professional Supervision: Ensures the process is safe and minimizes sensitivity.
• Even Application: The dentist can precisely apply the gel to all teeth, including those hard-to-reach molars.

Custom-Fitted Whitening Trays

Your dentist can create custom-fitted whitening trays that perfectly mold to your teeth. These trays hold the whitening gel securely against your teeth, maximizing contact and whitening effectiveness.

• Superior Fit: Custom trays provide better coverage and prevent gel leakage compared to over-the-counter options.
• Professional Strength Gel: Your dentist will prescribe a whitening gel with a higher concentration than you can find in stores.
• Convenience: You can whiten your teeth at home at your own pace, following your dentist’s instructions.

Over-the-Counter Options: Buyer Beware

While over-the-counter whitening products might seem like a tempting and affordable alternative, they often fall short when it comes to whitening back teeth.

Whitening Strips and Gels

Whitening strips and gels can be difficult to apply accurately to the back teeth. They might not reach the molars effectively, leading to uneven whitening. Furthermore, the concentration of whitening agents in these products is typically lower than what you’d find in professional treatments, resulting in less noticeable results.

Whitening Toothpastes

Whitening toothpastes primarily remove surface stains rather than bleaching the teeth. While they can help maintain brightness, they’re unlikely to significantly whiten your back teeth. The abrasive ingredients in some whitening toothpastes can also wear down enamel over time, so it’s important to use them sparingly and choose a brand recommended by your dentist.

Lifestyle Factors and Maintenance

Regardless of the whitening method you choose, maintaining your bright smile requires attention to lifestyle factors.

Diet and Drinks

Certain foods and drinks can stain your teeth. Coffee, tea, red wine, and berries are notorious culprits. Minimize your consumption of these substances, and rinse your mouth with water after you indulge.

Oral Hygiene

Brushing twice a day and flossing daily are essential for removing plaque and preventing stain buildup. Consider using a whitening toothpaste (under dentist supervision) to help maintain brightness.

Regular Dental Checkups

Regular dental checkups allow your dentist to monitor your oral health and provide professional cleanings. These cleanings remove stubborn stains and help keep your teeth looking their best.

Frequently Asked Questions (FAQs)

1. Can I use baking soda to whiten my back teeth?

Baking soda is a mild abrasive and can help remove surface stains. However, it won’t significantly bleach your teeth. Use it sparingly, as excessive use can erode enamel. It’s not recommended as a primary whitening method for back teeth.

2. Are LED teeth whitening kits effective for back teeth?

LED teeth whitening kits, often used with a whitening gel, might offer some superficial whitening. However, the effectiveness varies greatly depending on the gel’s concentration and the consistency of application. Reaching back teeth effectively remains a challenge with these kits, potentially leading to uneven results. Professional options remain significantly more reliable.

3. How long does professional teeth whitening last?

The longevity of professional teeth whitening varies, typically lasting from six months to two years. It depends on your diet, oral hygiene habits, and whether you use maintenance products like whitening toothpaste. Regular touch-up treatments can prolong the results.

4. Is teeth whitening safe for everyone?

Teeth whitening is generally safe, but it’s not recommended for individuals with sensitive teeth, gum disease, cavities, or exposed roots. Pregnant or breastfeeding women should also avoid teeth whitening. Consult your dentist to determine if it’s safe for you.

5. What causes teeth to stain in the first place?

Teeth staining can be caused by various factors, including:

• Diet: Consuming staining foods and drinks (coffee, tea, red wine, berries).
• Tobacco Use: Smoking or chewing tobacco.
• Poor Oral Hygiene: Inadequate brushing and flossing.
• Aging: Enamel naturally thins and becomes more porous with age.
• Certain Medications: Some medications can cause teeth discoloration.

6. How can I prevent staining on my back teeth?

Preventing staining involves good oral hygiene, minimizing staining food and drinks, quitting tobacco use, and regular dental checkups. Rinsing your mouth with water after consuming staining substances can also help.

7. Will whitening my back teeth make them more sensitive?

Teeth whitening can sometimes cause temporary sensitivity, especially with higher concentration bleaching agents. Using desensitizing toothpaste before and after whitening can help. Your dentist can also recommend techniques to minimize sensitivity.

8. How often can I safely whiten my teeth?

The frequency of teeth whitening depends on the method used and your individual sensitivity. Professional treatments can be done every six months to a year, while over-the-counter products should be used sparingly and as directed. Always consult your dentist for personalized advice.

9. Are there any natural ways to whiten teeth safely?

While some natural remedies like oil pulling and certain fruits might help remove surface stains, they’re not as effective as professional whitening treatments. Use caution with abrasive remedies like baking soda, as they can damage enamel. Always prioritize safe and gentle methods.

10. How much does professional teeth whitening cost?

The cost of professional teeth whitening varies depending on the treatment type and location. In-office whitening can range from $500 to $1,000 per session, while custom-fitted trays can cost between $300 and $600.

11. What are the risks associated with teeth whitening?

The primary risks associated with teeth whitening are tooth sensitivity and gum irritation. Overuse of whitening products can also damage enamel. Choosing a qualified dentist and following their instructions carefully minimizes these risks.

12. Can veneers or dental bonding help with discolored back teeth?

Veneers and dental bonding can effectively mask discoloration, but they are more invasive and expensive than teeth whitening. They are typically used for teeth with severe staining or other cosmetic imperfections. Veneers cover the entire front surface of the tooth, while bonding uses a tooth-colored resin to repair smaller areas. Discuss all options with your dentist to determine the best solution for your specific needs.
