An ounce of prevention is worth a pound of cure. Foods including dark berries and drinks such as coffee, red wine, and soda are known offenders, but you don't have to give them up. Enjoy these in moderation, and rinse with water right afterward so there's less chance they'll affect your teeth. (Wait 30 minutes before brushing to protect the enamel.)
However, lemon juice is acidic. If we were in your shoes, we would not use lemon juice for brushing our teeth, because the acidity may weaken your enamel and increase your chances of damaging it as you brush. We explain more on acidity in our articles “How to Drink Kombucha and NOT Destroy Your Teeth“, “Can Brushing After a Meal Damage My Teeth?“, and “Tracking Your Saliva pH“.
The disadvantage of brush on formulas to whiten your teeth is that you are instructed to keep you teeth completely dry for about a minute after you apply the formula. The mouth works against this because it constantly produces saliva, especially right after you have brushed your teeth. This can lead to undesirable results, when areas of the teeth you have treated are touched by saliva; in other words, you can get white spots on the teeth. On the plus side, careful application of brush on formula means minimal amounts get on the gums, so irritated gums are unlikely.
It makes sense that apple cider vinegar (ACV), which effectively works as a natural antibiotic and teeth/gum cleanser, would also be able to remove stubborn stains on the teeth. ACV is especially helpful for removing stains due to common culprits like coffee and nicotine (smoking). Some report that after using ACV it looks like you just got your teeth professionally cleaned!
I’ve appreciated the information in your site. My gums have improved considerably from your help. One thing I’ve come across that helps considerably to remove stains from my teeth ( I drink black tea) is a paste of lemon juice and baking soda. I hesitated to use this at first because of the acid of the lemon but found that when mixed with the baking soda it is very alkaline. Putting the paste on your teeth without brushing helps. There were a few worse stains the went away with a light rub with my finger. I also found a gum surgical technique that is very non invasive for those who want to restore gum tissue quickly and permanently. Better gums right away and minimal pain. It’s called the pinhole surgical technique and the process is shown on YouTube if you do a search.
For your daily oral care routine, swish one fluid ounce of mouthwash in your mouth after brushing and having meals for two to three minutes, and then spit it out. Ask your dentist or hygienist to recommend the mouthwash that is best suited to your individual needs. In some cases, your dentist might prescribe a stronger fluoride or antibacterial rinse for you.
Chew a piece of gum. Studies show that chewing sugar-free gum that contains xylitol for 20 minutes a day following meals can help prevent tooth decay. Chewing gum increases saliva production which in turn washes away food debris, neutralizes acids produced by bacteria, strengthens tooth enamel, and provides disease-fighting substances throughout the mouth.
What’s the secret of ACV? It contains compounds, including acetic acid, potassium, magnesium, probiotics and enzymes, which kill germs (dangerous “bad” bacteria) and at the same time foster the growth of beneficial “good” probiotic bacteria. Since it’s naturally acidic, it helps break down plaque or other substances stuck to the teeth. The pH of apple cider vinegar can remove stains from your teeth, which helps naturally whiten your teeth.
