When you first get your dentures, it may seem as if you're learning to talk all over again. Your voice may change as the sound echoes differently off the denture material. You may discover that some words are difficult to say because your tongue isn't used to the new dentures. Once your mouth adjusts to the dentures you'll be able to speak without any problems. You can help your mouth get used to speaking with dentures by reading out loud. If you notice a clicking sound from your dentures, you need to slow your speech and see your dentist for a possible fitting adjustment. Dentures will also decrease your ability to chew harder foods. You'll need to cut food into smaller pieces and learn to chew with an up and down motion to prevent dislodging your dentures. Once you're comfortable with your dentures and the fit is correct you shouldn't require adhesives to keep them in place. A dentist in your area can provide additional information on adjusting to and speaking with your new dentures.
