| Would appreciate if someone could tell me what the name of the hard
white part of the gum (at the top of the lower gum, or the bottom of the
upper gum) is, and what is the name of the operation in which a
transplant of this material is made.
Thanks.

At the necks of the teeth lie the free gingival margin. In a normal
periodontium you can insert a probe 0-3 mm before hitting a stop
(gingival attachment). The pinker part of the gum below this attachment
is the attached gingiva--that is, tightly attached to the roots and
underlying bone.
As you move away from the necks of the teeth, you will reach a point
where the tissue is redder, thinner, and more movable. This is known as
the alveolar mucosa.
Generally, you would like a minimum of 3 mm of attached gingiva around
the necks of the teeth to minimize chance of gum recession due to
abrasion. The type of surgery to correct inadequate attached gingiva is
broadly known as mucogingival surgery. There are several types of this
surgery. Some require grafting of attached tissue from elsewhere in the
mouth (usually the hard palate), some involve sliding tissue from an
adjacent gum area (some form of pedicle graft).

I have a bicuspid on the lower right that, I was told, lacks the
attached gingiva due to a congential defect. The red tissue is sagging
and the tooth is loose. I was told the options were a graft of attached
tissue, or synthetic tissue graft.
I was wondering why the tooth wasn't loose before if the attached
gingiva was missing all along.
Are there any other options that don't involve grafting?
Also, would appreciate any information on the pros and cons of the
options.
Thanks.

Mobility of teeth is a very variable finding in teeth with gingival
recession. Typically the recession is on the facial surface, and there
is little bone on that surface. But if the tooth is still surrounded on
3 sides by healthy bone, often there is little mobility.
I am not familiar with what synthetic materials are used for grafting,
nor their success rates. Obviously eliminating a second surgery at the
donor site is a very big plus. If the adjacent teeth have adequate
gingivae you can also sometimes do a submucous sliding pellicle graft
without using synthetics. The details and feasibility of these
different procedures should be discussed with your periodontist.
Good luck,
Steve
