I want to recommend that the reader consult with her or him personal doctor before trying any of these products. If there is a product that you think is effective for your teeth, I recommend that you contact the manufacturer of the product and ask them for a prescription.
There is much confusion over what causes dullness. The root cause of it is called tooth decay. If your teeth have started to rot in a few years and there is a chance that the root cause is dental disease, you should call a dentist and discuss the possibility of taking preventative actions. If there is no hope of getting a good dentist, call me. I can help you determine if any of the products listed above are effective and how long it might take to get results. My contact information is listed on the next page. If you are interested in purchasing a dental crown, you may find my recommendations on purchasing a crown helpful. Some products can be used for a few days without any side effects, but there are times when the results are more dramatic. This is usually the case if you are going through an extreme period of stress, when there is no money to pay for dentures, or when you have a dental emergency.
