A denture is a removable replacement for missing teeth and surrounding tissues.
There are two types of dentures are available -- complete and partial dentures.
Complete dentures are used when all the teeth are missing, while partial dentures are used when some natural teeth remain.
Here, we will discuss about complete denture. To know about Partial dentureClick here.

Complete Dentures
Complete dentures can be either "conventional" or "immediate." Made after the teeth have been removed and the gum tissue has begun to heal, a conventional denture is ready for placement in the mouth about eight to 12 weeks after the teeth have been removed.
Unlike conventional dentures, immediate dentures are made in advance and can be positioned as soon as the teeth are removed. As a result, the patient does not have to be without teeth during the healing period. However, bones and gums shrink over time, especially during the healing period following tooth removal. Therefore a disadvantage of immediate dentures compared with conventional dentures is that they require more adjustments to fit properly during the healing process and generally should only be considered a temporary solution until conventional dentures can be made.

Alternatives to Dentures
Dental implants can be used to support permanently cemented bridges, eliminating the need for a denture. The cost is usually greater, but the implants and bridges more closely resemble the feel of real teeth. Dental implants are becoming the alternative to dentures but not everyone is a candidate for implants. Consult your dentist for advice.

Procedure to make  Dentures
The denture development process takes about two weeks and several appointments. Once your dentist determines what type of appliance is best for you, the general steps are to:
  •   Make a series of impressions of your jaw and take  measurements of how your jaws relate to one another and  how much space is between them.
  •   Create models, wax forms, and/or plastic patterns in    the  exact  shape and position of the denture to be made. You  will "try in"  this model and the denture will be assessed for  color, shape,  and fit before the final denture is cast.
  •       Cast a final denture
  •       Adjustments will be made as necessary.

Some Common Problems with New Denture

·        Feel With New Dentures
New dentures may feel a little odd or loose for a few weeks until the muscles of the cheeks and tongue learn to keep them in place and you get comfortable inserting and removing them. Also, it is not unusual for minor irritation or soreness to occur and for saliva flow to increase when you first start wearing dentures, but these problems will diminish as the mouth adjusts.
·        Look with New Denture
Dentures are made to closely resemble your natural teeth so there should be no noticeable change in appearance. In fact, dentures may even improve your smile and fill out your facial appearance.
·        Eating With New Dentures
Eating with new dentures will take a little practice and may be uncomfortable for some patients for a few weeks. To get used to the new denture, start with soft foods cut into small pieces. Chew slowly using both sides of your mouth. As you get used to new dentures, add other foods until you return to a normal diet  Avoid foods that are extremely sticky or hard. You may want to avoid chewing gum while you adjust to the denture.
·        Speaking With New Dentures
   After getting dentures, you may have difficulty pronouncing certain words. If so, practice by saying the difficult words out loud. With practice and with time you will become accustomed to speaking properly with dentures, usually it takes 3-7 days.
If dentures "click" while you're talking, contact your dentist. Dentures may occasionally slip when you laugh, cough, or smile. Reposition the dentures by gently biting down and swallowing. If any speaking problem persists, consult your dentist.
·        Wearing time of New Dentures
Your dentist will instruct you as to how long to wear dentures and when to remove them. During the first several days after receiving your denture, you may be asked to wear it all the time. Although this may be temporarily uncomfortable, it is the quickest way to identify the areas on the denture that may need adjustment. You should remove dentures before going to bed. This allows gum tissues to rest and allows normal stimulation and cleansing by the tongue and saliva. The denture can be put back in the mouth in the morning.
·        Use of  Denture Adhesive
A denture adhesive may be considered under the following circumstances:
a.  To enhance satisfaction with a properly constructed denture. Adhesives enhance retention, stability, bite force, and an individual's sense of security.
b.  To assist individuals with dry mouth conditions that lessen denture adherence, such as individuals taking cold medications, those with neurologic disabilities including strokes, and the elderly.
c.   To provide added stability and security for those who place unusual demands on facial muscles, such as public speakers or musicians.

·        Tips to use Denture Adhesives
Here are some tips to consider when applying denture adhesives:
Use the minimum amount necessary to provide the maximum benefit. Apply less than you think you need, and then gradually increase the amount until you feel comfortable.
Distribute the adhesive evenly on the tissue bearing surface of the denture.
Apply or reapply when necessary to provide the desired effect.
Always apply the adhesive to a thoroughly clean denture.
Remember adhesives work best with a well-fitting denture. 

General Advice  
·  Be sure to leave your dentures out overnight. Dentures should be stored in a covered container with the cleaning solution when not in the mouth.
·        Generally the upper denture will be better than the lower. 
    One must learn how to use and retain the lower denture.
·    In the beginning, do alone, as much talking, reading aloud and eating as possible. This will allow you to avoid embarrassing moments as you learn to use your new dentures.
·       In time, due to continued resorption of the jaw, your dentures may require relining. 
·       Have your dentures, mouth, and adjacent structures checked by your dentist at least once a year. The needs and nature of each patient vary, therefore, check with your dentist about anything not covered here. 

·  Dentures can be regarded as the best dentistry treatment option for the people who can not choose dental implants for some reasons like age or health conditions.

· Dentures can also fulfil the need of a cosmetic dental treatment giving the patient a better appearance, better look and the confidence back again.
