Complete DenturesnnComplete dentures are used when all of the teeth are missing. In our office, we make immediate dentures, meaning that on the day that your teeth are extracted, you immediately receive your denture so that you never have to go without teeth. Immediate dentures will shift a little bit as the tissues heal and will need to be relined at a future visit, usually six months later.nnPartial DenturesnnPartial dentures are used when some teeth are missing but some remain. Partial dentures also prevent the remaining teeth from drifting over time. Partial dentures are a mixture of metal clasps that can hang on to your existing teeth and acrylic, which is used to restore the missing teeth.
