The main idea is to make your teeth and gums brighter and healthier. This may not always be practical. A few products may be a good choice. My experience is that there are two main problems with all the products available: They don't work; the cost may not be worth it.
If you want a simple method of brightening teeth, here's what I do: 1. I use a toothpaste that is made from food-grade coconut oil. This means that it is extremely safe for you. It's very effective in brightening teeth, even if you haven't used them for many years. I'm very happy with it! 2. I also use a very effective food-grade baking soda in a container that is easy to keep clean. I keep it in a small cup in the fridge or freezer, and I also use it to wash my hands after I've applied my product. It's very effective at keeping the moisture out of the mouth. I've found that the toothpaste really helps me get my diet right, and also helps my smile. 3. I use a product called Dermabrasion, which is an acid based product, to brighten my teeth. I think it is great for children who are too light to get the dentures in.
