The antibiotic tetracycline causes gray teeth in children whose teeth are still developing. Antibacterial mouthwashes that contain chlorhexidine or cetylpyridinium chloride can also stain teeth. Some antihistamines, antipsychotic drugs, and blood pressure medications cause tooth stains, as can iron and excess fluoride. If bleaching doesn't help, ask your dentist about dental bonding, in which a tooth-colored material is applied to teeth.
I had to get some partial veneers near my molars because a former dentist pulled one too many teeth and there was an awkward space left after I got orthodontic work done. So, I won’t even go close to these teeth with activated charcoal. Using the charcoal on teeth without cosmetic work is fine and my personal results were quite noticeable after three uses.
One of the reasons we brush our teeth is to increase the saliva in our mouths to provide our teeth the necessary remineralization that occurs from contact with lots of saliva. However, if we brush with activated charcoal on a daily basis, our concern is the charcoal’s binding ability will tie up the minerals necessary and inhibit this important remineralizing action of saliva.
I called many American Companies like mountain rose herbs , redmond clay ,aztec clay and when I asked them about lead in their clay they said that every clay comes from the earth and that is why there is tiny amount lead in the clay, but it occurs naturally so it is bind with other elements in the clay and does not leak in the human body , so the human body can not absorb the naturally occuring lead in clay.
Once I became pregnant with our first child, I was careful to avoid all chemicals, including those normally used to whiten teeth. I wanted to find natural ways to whiten my teeth that not only worked well, but were also safe. Since chemicals can easily absorb through the sensitive skin in the mouth, I wanted to only use options that were safe enough to eat.
If I were in the shoes of a person with this situation, I would exhaust natural methods first before shifting to bleaching. For example, I’d do a ’30 day oil pulling’ commitment for myself. Everyday for a month, I’d oil pull and take ‘before and after’ photos so I could see the changes. That way, if I still wasn’t satisfied with the whiteness, I would know that I had tried less invasive strategies prior to choosing a method that may challenge my teeth.
4. Baking Soda: Baking soda is widely known for its uses for household cleaning and whitening. Baking soda is among the easiest and most efficient ways to naturally whiten teeth. Baking soda is slightly abrasive and helps remove stains on teeth. Simply just brush teeth with baking soda mixed with a little water to create a paste. Or you can use a mixture of baking soda and coconut oil. This is also a great homemade toothpaste. I use baking soda and coconut oil to brush my teeth every day.
Teeth whitening strips may be more appropriate for the person who has more yellow teeth. These are plastic strips coated on one side with hydrogen peroxide. They can be used nightly for two to four weeks depending upon the degree to which you want to produce a lighter shade. They still are not as effective as dental whitening, but they can create lighter teeth. Most four-week kits cost between 20-40 USD. The strips don’t necessarily adhere completely to the teeth, and there may be more whitening in front than in the back of each tooth.
Some people — no matter how many times they brush their teeth — have teeth stains from habits like drinking coffee or tea and/or smoking. Oftentimes yellow- or brown-tinted teeth can also point to a larger problem: unhealthy gums, thinning enamel and overall poor dental hygiene. Whitening the teeth alone won’t help protect the teeth or gums from cavities or diseases, such as gingivitis — so while white teeth are certainly a nice thing to have, it helps to keep things in perspective.
