Van thanks for the tip. I'll file that for further use.
Regarding the teeth, in Ayurveda when you eat a lot of food that aggrivates Pitta (don't worry about what that means for now) the heat or Pitta builds up in the seat of Pitta. (the stomach) When it gets too much for that area it starts to spread.
Since Pitta is essentially heat it naturally flows uphill. Since your mouth is uphill from your stomach the Pitta migrates to your mouth. A goiter is another symptom. This excess heat eats away at the mucous membrane in the mouth and the gums and brings on a variety of symptoms of which rotting teeth is one, cankers is another (my isssue) A friend of mine's ex was so in love with sour food and drink that her Pitta was out of whack for years, resulting in dental pain so intense that she tried the anaesthetic toothpaste (Sensodyne) which is a very bad idea no matter what your dentist tells you.
Then at her wits end with pain, she had all her teeth removed.... ouch! I tried to tell her the sour food and drink was the problem, but her sour and foul temper kept her from changing her habits. She ended up having a nervous breakdown and incredible fits of anger problems which sunk her marriage, but that's another story.
Essentially the sour (Pitta) eats away at the teeth causing holes which get infected and the gums recede and expose the root of the teeth causing huge pain. When you run your fingernail down your tooth to the gum you will notice a depression at the juncture. If this depression is pronounced then you have or will have dental pain when the root is exposed to air or cold or hot. If you go to a dentist with this issue, initially they will simply paint something that my dentist called lacquer or varnish (I forget which) but it literally just coats the area. Nothing more. It is a stopgap because if you continue eating sour, salty foods that aggrivate Pitta, the gums teeth will continue to deteriorate and next step is classified as periodontal disease (I believe) This is very expensive and painful etc.
Solution -
ditch the
fruit,
anything sour , sugar (anything but honey) salty flavours, hot or spicy or pungent foods such as pepper or chilis, onion, garlic and so forth. If you have honey absolutely get raw unheated honey and have it with an equal amount of raw unheated butter.
Basically avoid - sour, salty and pungent foods period, no matter how much your nutritional theories suggest them. Reduce water intake also.
Favour sweet tasting foods like chicken, beef and foods that taste sweet without processed sugar. Favour sweet, bitter and astringent foods.
The lists are long and so to get a better idea go to
http://www.ayurveda.com/online_resource/index.html and click on Food Guidelines under Food and nutrition guidelines. Then look under Pitta and follow the columns of favour and reduce. These lists cover all the basis no matter what diet you are following. Dr Lad is a vegetarian but he is also a Doctor of Ayurveda which is not traditionally a vege system so he lists everything. You pick what you want.
Aajonus also suggests eating fats whether it be from butter, avocado etc when you eat fruit, but if you have serious issues, just give up the fruit. You will see a gradual increase in dental comfort or issues will subside depending on how bad they are. Your body type sounds like you have a Pitta imbalance.
Honestly I cannot for the life of me imagine why anyone would try to live on fruit. But that's just me. For some body types more fruit can be tolerated, but not a Pitta. I get cankers (open mouth sores) from just about thinking about eating fruit : )
