The solution depends on the problem.
- If you have a sore spot or pain in one area
Sometimes it may just be a matter of applying something called Fitchecker (or equivalent)- a special paste that highlights any parts of the underside of the denture, that may be too high and need relieving.
Fit checker (or pressure indicating paste) is first mixed and put on the inside of your denture. It is then sat in the mouth whilst your cheeks are moulded by the dentist, before being asked to bite together and stay together, while the material sets. This will show any high spots or over extended areas that need to be adjusted.
Sometimes a special pencil is used to apply a bit of dye to the ulcer or area of redness and when the denture is placed in, the dye transfers to the denture showing the corresponding part that is causing the problem.
After the area is adjusted – assuming the dentist gets the right spot, you should feel some instant relief. The area is still going to be sore, especially if there is a nasty ulcer, until some healing has taken place. It is best to leave out the denture as much as you can and do some warm, hot salt rinses to speed your recovery.
The dentist will want to recheck you in 1-2 weeks and further adjustment may be needed if you haven’t fully healed. Areas of denture hyperplasia (gum growth) may take up to 6 weeks to subside, after which, if they haven't fully some minor surgery may be needed to remove them.
Then it may be a matter of just adjusting your denture teeth a little bit at a time. Here, we will use some articulating or ‘bite’ paper (a very thin inky paper) that marks your teeth when you tap down on it and ask you to bite together and scrunch your teeth around.
It is the same process for checking the bite after a filling. Adjustments will be made until your teeth meet more evenly at the back on both sides, and your bite feels comfortable.
It depends on the cause of the looseness- in cases where an excellent denture is made but the issues stem from ‘you factors’ such as unfavourable anatomy (e.g. a lack of ridge form) or absence of much needed saliva then denture fixative
may be required or implants into which the denture can be attached and held in place. If the looseness comes from resorbtion of the ridges and the denture no longer fitting closely against your gums then a denture reline
can be performed.
There are far too many possibilities to cover here; I wanted to just give you a couple of examples to help you appreciate the relm of complete dentures.
If you have had a series of unsuccessful dentures, it suggests that your case may be a little more tricky and in these cases, instead of having a regular dentist add to the collection, it may be advisable to see a specialist- at least for an opinion. This may be a prosthodontist, or at a teaching facility if you can get in. Sometimes, it is more about appreciating the limitations of your situation, than it is about getting a 'decent' set of dentures made. Perhaps a dentist may modify an old denture to see if they can improve things first somewhat before going ahead and making a new one.
