Partial dentures and bridges cost less and are less invasive than other forms of tooth replacement, reports the New Hampshire Center for Comprehensive Dentistry. One of the major drawbacks of wearing a partial is that it takes time to get used to having the denture or bridge in the mouth.
In some cases, it is possible to add teeth to a partial over time, states the New Hampshire Center for Comprehensive Dentistry. This eliminates the need to pay for another partial, reducing the cost of tooth replacement. Some people have an easier time adapting to a partial than to a complete set of dentures. Partial dentures also fill in the spaces left by missing teeth. This prevents the remaining natural teeth from changing position, as stated by WebMD.
Although there are several benefits associated with wearing partial dentures and bridges, partials also have some drawbacks, according to Gallardo & Lamas Periodontics and Implant Dentistry. There is no secure bond between the partial and the gums, increasing the risk that the partial slips around in the mouth. If the partial slips out of place, it is difficult to chew or speak properly. Ill-fitting dentures also cause irritation and sores in the mouth. In some people, aging causes the gums to shrink or pull away from the teeth, changing the way partials fit. As a result, partial dentures and bridges may need to be replaced periodically, as recommended by Werrin, Gruendel & Boles.
