Hi Mati, I really sympathise with your situation! I think you may find a lot of contradictory answers, because I dont know if anybody will no the ideal route you should take... only you can really make the final decision.

If it were me? I would save the tooth with the small filling and have that replaced with a good strong biocompatible material (e.g. cerec).

The other tooth with the large filling? Depending on how big the filling is and whether it is worth saving a tooth that might already only be held together by the filling itself. If it is worth saving? I'd probably do the same as the above. If not, I'd have it removed.

Removing teeth can also cause some potential problems. E.g. cavitations. If you haven't heard this before, cavitations can be caused by a tooth being removed without removing the periodontal ligament as well. Plus vaso constrictors in anaesthetic (due to slowing down blood flow and therefore healing to the area, frustrating bone growth over the hole).

The ligament is a little like the ambilical cord for the tooth. Problem is, when the tooth has been removed and the ligament left behind? There is no more function for it, so it can sit and rot underneath. Meanwhile healing occurs over the top and usually no external signs of a problem, whilst underneath a condition can form, which is similar to wet gangrene.

So if the cavity is not cleaned out thoroughly, the bone is not able to grow across the gap properly and therefore it is ripe for the growth of potent bacteria. This has the potential of causing systemic illness, sometimes as bad, if not worse than mercury toxicity.

Many people have cavitations and seem "ok", and so often this is because their immunity is keeping the problem localised. But sometimes the bacteria can spread and become systemic, especially if a person is already compromised in some way.

They are very tough to spot on xrays, and often are quite invisible. Hidden cavitations they are called. And often do not show any signs of a problem in the mouth (swelling etc), but sometimes they can.

Another cause of these is the use of vaso constrictors in local anaesthetics. vaso constrictors serve to increase the numbness to the area and prevent blood flow. The dentist like using them because they slow down bleeding and increase the length of the time of numbness, which would appear to be beneficial. In fact, I have read that they can contribute to dead teeth. How true that is? I don't know.

Problem with this is, the lack of blood flow to the area for such an extended period of time, can slow down or even prevent proper healing (e.g. bone growth). So again, another risk for cavitation formation.

Add this to a compromised immunity that may also slow down healing, and you can see how jawbone cavitations can occur.

So if you want to get teeth removed? I would suggest finding a good biologic dentist and requesting a NON vaso constrictor, non epinephrine anaesthetic (tell them you are intolerant to them if you wish), and request that the periodontal ligament be removed along with the tooth.

Also it is wise to have the area stitched, rather than packed. Packing may also interfere with healing.

I know it sounds extensive, but if you find the right dentist who is aware of cavitations, he should already understand this.

Other than that? There is the only other option of replacing the amalgam. Your chemical sensitivity is shared by many on here and if you feel that it is too risky to put in a foreign material? Then you may prefer to opt for removal.

HOwever, one lady I knew on here who was also very chemically sensitive, opted to have cerec porcelain and is tolerating them fine. But again, everybody is different and there is no one fast rule.

Wish there was! Also it is a case of finding an honest dentist who will LISTEN to your needs and discuss the better option and if you request amalgam removal, or removal, then he/she should be relied upon to do a thorough honest job.

You can always find a way to email some in your area first.
Also, severe MCS is often a sign of mercury. So it's a problem because the mercury can cause you to become highly sensitised to almost anything and evrything and therefore just about any replacement material may seem to be a problem. Detoxing mercury can often improve or even resolve this.
