Hello, Thank you for contacting Healthcare Magic. I need to confirm that you are calling a removable partial denture artificial teeth? Do you have a plate that fits on the roof of your mouth? New denture wearers have an adjustment period, but I do not expect this to continue for months. Common issues that affect speech include: -excess saliva -tongue movement -adjustments needed to teeth and bite You will have excess saliva until you get used to something in your mouth. Your tongue has to get used to the plate covering the palate. If the tongue feels restricted, ask if an adjustment can be made to reduce the amount of material or thickness of material on the plate. If the position of the teeth affect your speech, the bite can be adjusted. This is often a simple reshaping to improve how your teeth meet or a slight reduction to the edge of teeth to shorten the length. Most often, time and practice will resolve your speech difficulties. Try an astringent mouthwash to reduce saliva. Return to your dentist for an adjustment if you do not feel your speech improve, but be patient. If you do not notice an improvement in a couple of weeks schedule a visit. Also, if you develop sore spots, schedule a visit for a simple adjustment. a less common occurance is an allergic reaction to the materials used. If you have a fixed bridge and continue with speech difficulties, you will need the dentist to adjust your bite. Call for an evaluation follow up visit. I am available to answer additional questions and hope you will not continue with speech difficulties after following my suggestions. I hope you find my reply helpful.
