Using Household Bleach on Teeth Safely and Effectively
Household bleach contains sodium hypochlorite, which can disinfect surfaces and whiten teeth. But is it safe and effective to use on your teeth? Bleach offers an affordable alternative to commercial whitening products. However, it also comes with risks if used improperly.
How Bleach Works to Whiten Teeth
Bleach contains reactive oxidizing agents that break down stains and discoloration on the enamel surface. This helps restore a brighter, whiter color to teeth. Things like coffee, tea, red wine and tobacco can cause yellowing over time as pigments build up in the enamel.
The oxidizing compounds in bleach work to penetrate and dissolve staining compounds. However, they can also damage the enamel if misused, so caution is required.
Determining If Your Teeth Are Suitable
Bleach may not be the best choice for teeth that are already worn, damaged or decayed. The chemical compounds can seep through cracks and worsen sensitivity. Heavily restored teeth or dental work like crowns and veneers can get damaged by bleach.
Consult your dentist before using any bleach products. Get any necessary dental work done first, like fillings or root canals. Make sure your gums and mouth tissues look healthy with no sores or irritation. Address any outstanding dental issues to ensure your teeth can withstand bleaching.
Safety Precautions When Using Bleach
Never swallow or ingest bleach - it can poison or kill you. Be extremely careful to only use it topically on your teeth. Bleach also irritates and burns soft tissues like gums, cheeks and lips. Avoid contact with any oral tissues during the whitening process.
Work in a well-ventilated area and use gloves to protect your hands. Bleach can irritate eyes and nasal passages with its strong fumes. Keep bleach away from children and pets - ingestion can be fatal.
Start by diluting the bleach properly to a safe concentration. Test it on a small area first to check for sensitivity or burning before applying it to the full set of teeth.
Effective Bleach Concentrations for Whitening Teeth
Mixing bleach with water dilutes it to a gentler concentration for the sensitive enamel on teeth. Here are some commonly recommended ratios:
- 1 teaspoon bleach to 2 cups water - approx 0.1% concentration
- 1 tablespoon bleach to 1 cup water - approx 2% concentration
- 1/4 cup bleach to 1 cup water - approx 6% concentration
Higher concentrations like 6% provide more intense whitening, but also increase the risk of enamel damage and sensitivity. Start with a 0.1% or 2% solution to assess your teeth's tolerance.
Options for Applying Bleach to Teeth
Here are some techniques for using diluted bleach as a teeth whitening treatment:
- Use as a mouth rinse and swish around teeth for 1-2 minutes before spitting out.
- Dip a clean toothbrush in bleach and gently brush teeth for 1-2 minutes, then rinse mouth.
- Use bleach soaked cotton swabs to dab and rub stains off individual teeth.
- Put bleach in a dental tray mold and wear for 30-60 minutes like a bleaching gel.
Try several applications about a week apart to see desired results. But limit bleach use to avoid over-whitening or enamel damage.
Using Bleach Whitening Strips
Applying bleach to whitening strips offers a mess-free way to target teeth. Try soaking small cotton strips in the diluted bleach solution. Then place the bleached strips on teeth for 5-10 minutes before removing and rinsing.
This targets the bleach directly onto enamel, avoiding contact with gums. Pre-coated whitening strips sold in stores contain lower hydrogen peroxide concentrations, not bleach.
Making a Bleach Whitening Toothpaste
For a gentler approach, adding a small amount of bleach to your regular toothpaste can create a light whitening effect over time. Try mixing in 1-2 drops of bleach per use.
This low concentration gets well dispersed in the paste and acts as you brush normally. Monitor for sensitivity and discontinue use if any burning or discomfort occurs.
How Long Does Bleaching Take to See Results?
You may notice a slight difference right after bleaching, but full effects take repeated applications. It can take 7-14 days of periodic use to see significant whitening. Results also depend on the original degree of staining and discoloration.
For heavy tobacco or tetracycline stains, bleach may lighten but not completely remove spots. Manage expectations, as bleach works best for mild yellowing. Touch up periodically as stains slowly return over time.
Risks and Side Effects of Bleach Whitening
Used incorrectly, bleach can damage enamel and irritate oral tissues. Potential side effects include:
- Tooth sensitivity - Bleach seeps through microscopic enamel cracks.
- Gum irritation - Bleach burns and inflames gums if it makes contact.
- Enamel erosion - High concentrations weaken and degrade enamel.
- Oral thrush - Bleach kills good mouth bacteria allowing yeast overgrowth.
- Canker sores - Bleach aggravates and causes mouth ulcers.
Stop use and see a dentist if you experience any burning, intense pain, gum damage or other problems. While effective, bleach carries substantial risks.
Special Considerations for Dentures and Veneers
Soak dentures for no more than 3-5 minutes in very diluted bleach to avoid cracks and warping. Veneers and crowns get damaged by prolonged bleach exposure, so minimize use.
Avoid bleaching right before dental visits for new veneers or crowns. Wait until after they get placed so bleach doesn't compromise bonding strength.
Alternatives to Bleach for Natural Whitening
For a safer approach, try these natural teeth whiteners:
- Baking soda - Gently abrasive to lift stains.
- Hydrogen peroxide - Breaks down discoloration without damaging enamel.
- Coconut oil - Contains fatty acids to break up plaque.
- Fruits - Pineapples, strawberries and oranges contain enzymes that whiten.
- Vegetables - Carrots, celery, apples and broccoli scrub teeth clean.
These whiten without harsh chemicals like bleach. But they work more gradually, requiring consistent use to see results.
When to See a Dentist About Your Teeth Whitening
Consult a dentist if you experience:
- Extreme tooth or gum sensitivity
- Changes in tooth structure, shape or integrity
- Increased cavities or tooth decay
- White spots signaling enamel damage
- Gum recession or exposed tooth roots
Professional whitening under a dentist's supervision costs more but causes less damage than bleach. They also check for oral cancers and other problems aiding early detection.
Achieving Whiter Teeth Safely
Used judiciously, household bleach offers a cost-effective whitening solution. But misusing it carries risks of enamel erosion, gum damage and tooth sensitivity. Minimize use, dilute bleach properly and stop immediately if you experience any discomfort or side effects.
