Throughout your lifetime, dentures will need to be replaced and adjusted which can become time consuming and expensive. It is a simple fact that dentures start to become loose and can break through normal activities such as talking, eating, etc. If a denture arch breaks, it may be possible to repair but in some cases it will need to be replaced entirely.
I had 16 teeth pulled and plates made for under $1,000. I went in in the morning and had new teeth the early the next morning with the main cost being $40 a tooth for pulling which took about a half hour. The upper fits well and I have been getting by with lower, need it refitted but do not have the doe re me at present. It is just crazy what dentists and doctors charge for routine proceedures here in the US.
Teeth can fall out for a number of reasons, ranging from genetics to drug abuse. Most commonly, teeth are removed or fall out on their own due to severe tooth decay. Neglect to upkeep oral hygiene or not seeking proper treatment for damaged teeth, can lead to the onset of decay which in turn leads to loss of teeth. Visiting you dentist in 6 month intervals is a good preventive measure to spot any early signs of decay.
