Changes in the mouth resulting from the loss of teeth may cause changes in speech. But replacing teeth with dentures actually can improve speech.

Dentures also can cause vocal changes. This is due to the position of the jaw and the thickness of the part of the denture that covers the roof of the mouth (palate). These can change the position of the tongue. After getting dentures, some people have increased their vocal range.

About 1 of every 4 denture wearers notices at least temporary difficulties with speech. In most people, these don't last long - often, only about a week. If you continue to have speech difficulties, your dentures can be remade.

At the age of 70, you are probably not going from having all your teeth to full dentures. Partial dentures cover less of the gums and palate. They usually are made with a thinner metal framework than full dentures. Partial dentures are much easier to get used to.

As another option, you might want to consider dental implants. They are costly, but they are better at simulating your natural teeth.
