Yes, you should go back to the doctor that extracted the tooth. This is probably what is called a dry socket.

No, once the teeth are formed there is no more Ca uptake in the teeth. Any advantages would be surface oriented. There are other ways to get calcium anyway. He should see a dentist .

First, dental treatment can be done while you are pregnant, especially if there is an infection like a root canal. But, your gums can be more sensitive just from not brushing well, your gums can become more swollen and irritated from the hormonal changes. Get your teeth cleaned, possible topical fluoride treatment and toothpaste for sensitive teeth.

Gum lacerations usually heal well without doing anything. It is better to leave them open especially if associated with an external laceration. But, signs of infection would be pain, swelling, redness, exudate or any drainage, and it is not healing like it should.

Go back to the doctor that did the filling. The filling just might need adjusting.
There could be an infection starting and my need a root canal. These are the most common reasons.

First, make sure you do have periodontal disease. Periodontal disease causes "pockets" around your teeth which makes it difficult to clean by brushing only since the bristles of the brush don't get deep enough. This is why it is important to see your hygienist more frequently.
Periodontal disease can run in families because the aggressive bacteria can be passed between members of the families especially parents and kids as they grow up. This is a simple answer to your question.

These are called aphthous ulcers and the exact cause is unknown but is related to immunogenic systems. The first time you get them the there are more likely to be larger and sometime more in numbers. As your immunity builds up to these they aren't as bad usually. As they re occur they can come back in the same locations.
Many things can exacerbate them such as stress, acidic foods, trauma. and recent studies suggest vitamin deficiency ie. B 12, C, iron, folate.
There are various treatments, most are symptomatic relief. Anything over the counter with benzocaine will help with pain, Orabase,Cankaid ect.

Now, one of the best treatments is the use of a laser with will relieve pain and make the healing process much faster and is a simple procedure.

This is a basic answer to that question. Once a tooth is extracted, bleeding occurs which is good. The blood fills in the hole and clots. This blood clot allows cells to form new bone to cross from one side of the hole to the other, sort of a scaffolding. If there is no blood clot, it exposes the bone and nerve endings in the extraction socket, so it is a "dry" socket. The cause for the blood clot not being there could be not enough bleeding when the tooth is extracted, infection, blood clot is washed out, the body dissolves the clot. Cleaning the socket out so it bleeds again, removing infection and packing the socket with a special paste are things the dentist will do to treat it.
