Denture Photos

Good morning. It is a question about a son - a person who is 30 years now. Probably good idea to visit the doctor, but it is expensive, and we're more than that different doctors give different answers.

Is it possible to guess from the photos attached, is there any way this guy to save teeth?
The teeth are cleaned regularly and appropriate at least twice a day for about 3 minutes, or a Listerine twice a day, flossess are provided. But something like periodontitis or periodontitis and poorly aligned front teeth and the strength of his front teeth are probably three major problems.

In 1979, he was born in 1990, his top front tooth was broken because of the fall on the metal box. Thus, he lost about 15% a tooth on the front.
1994 - he braces for his lower jaw. It was recommended to have braces on the upper jaw as well, but he has not done that. So the doctor told the broken tooth should get the same size when a boy reaches 18 years or something like that, without any help. Unfortunately, this has not occurred.

Once or twice dentists lengthened his broken tooth so that the tooth has the same length as normal. The last time she was about 5-10 years before moving to the United States. Now, it's shorter again because the tooth filling is not as strong as the tooth - we do not know. Probably good idea is to lengthen the front tooth again.

Now the problem is the following:
-The difference between the lower front teeth to about 1 millimeter. At least 2 years ago we did not see any difference.
-The tissues surrounding and supporting the teeth (the gums) disappear. It is not certain changes in the last two years, although this is certainly not better.
"When he tries to check with his fingers, what is the strength of his four front teeth, he thinks they are not very strong.
- He read a lot of literature he supposed to eat healthy foods and he does, eats several times a day, lots of fruits and vegetables, rice, oats, no fast food, no chips, no soda. Sometimes he eats chocolate. Also, he knows he supposed to eat hard food - apples, carrots, etc. - is good for his gums and teeth, makes you stronger - anything that reduces the likelihood of increasing periodontists process.

Facts:
- In 2005, he asked about the availability of devices to align her teeth. He was told by the doctor that the structure of language does not make dentures. Something as it moves from its teeth his tongue.
- In 2006, he was told by another dentist that everything is OK and the only problem is that too hard to clean his teeth - is the result of periodontitis (I do not know this word). So do not brush too hard and you'll be fine. There's nothing else you have to do.

- Now he thinks that good idea is to increase the length of the broken tooth, because the difference between the teeth level should be reduced, and probably it will reduce the risk of losing four front teeth.
- Another problem is that in a year this guy has to move to another country. This means that this is not a good idea to obtain prostheses immediately even if it is recommended.

Please help decide what to do - to visit a doctor is OK, but the doctor will tell us how to spend money, not how to save teeth.

Another fact is that in the last 12 months there were no significant changes in the structure of the teeth (this guy measured the length of the periodontal pockets of front teeth). Thus, we hope that the speed of this process has been greatly reduced. But how to do better, not only recude this process?
So he used special creams for periodontal gum, but it sees no changes after use.
Here are 10 different pictures of teeth:
