risks / side effects

Like any medical procedure, the use of TADs also carries some risks and may create certain side effects that you should be aware of. You will be happy to learn though, that significant risks and side effects to date have not been reported.

Below you will find a list of various issues that may arise, in alphabetical order. While this list tries to provide as much information as possible, no claim is made that it is complete and all-inclusive and necessarily applies to your situation. Please read our disclaimer for more information.

Adverse reaction to local anesthesia:

As was explained in the section TAD placement, this procedure requires the use of a small amount of numbing agent, either a topical gel or an injection. On rare occasion the components of the anesthetic may create certain side effects such as irritation of your gums, allergic reactions, increased blood pressure, increased heart beat, or other side effects. Please inform your doctor of any general heath problems or bad reactions you may have previously experienced as a result of dental anesthetics.

Ulcerations of the gums:
Localized ulcerations can occur as a result of mechanical tissue irritation. While they may cause discomfort at times, they are not infectious and usually heal once the TAD is removed.

Nerve involvement:
It is extremely rare but theoretically possible that a TAD will encroach on a nerve and possibly damage it. Nerves have the ability to heal, but altered sensations or numbness may persist if this happens.

Paranasal sinus / nasal cavity involvement:

The upper jaw is closely related to the nasal cavity and the paranasal sinuses. Therefore, depending on your individual anatomy and the insertion site of the TAD, considerable risk exists that the insertion may involve either one of these cavities. This usually goes unnoticed and does not cause any problems. Rarely, it can lead to discomfort, a sinus infection, the formation of a cyst, and/or nose bleeding. These rare side effects usually disappear once the TAD is removed.

Post-operative discomfort:
Some degree of discomfort is common after the insertion, especially if the TAD was placed between the roots of two teeth. It is generally felt in the form of pressure that gradually improves and usually disappears within a few hours of the insertion. On occasion the pressure may last longer though, up to a few days.

TAD loosening - failure:
TADs, as was explained in the section General Principles, are intended for temporary use only. Therefore they will never connect with your bone the way a regular dental implant does - we want to be able to remove it easily. This means however that at times, the TAD may become slightly loose a few weeks after the insertion. This is not uncommon and given a favorable environment, it often times stabilizes again. However sometimes, it loosens to the point that it is no longer held in place properly and hence cannot provide reliable anchorage anymore. Your body rejected the TAD which constitutes a failure. This is usually not painful but may complicate matters since the implant may need to be replaced.

TAD fracture:
It is possible that TADs can break during the placement or the removal. If this occurs, the broken piece can either be removed or left in place since it is made of titanium.

Tissue irritation / overgrowth:
This may be the most common side effect. Depending on the quality of the gum tissue surrounding the TAD some level of irritation can be observed at times. The tissue then appears swollen, red, may bleed easily, and it may be more sensitive that other areas of your mouth. Sometimes your tissue will even cover the TAD completely, leaving behind only a raised area in the gums. This will require a re-exposure of the TAD. Irritation and overgrowth usually disappear on their own once the TAD is removed and can be minimized by good oral hygiene.

Trauma to the roots of teeth and the periodontal ligament (PDL):
When placed close to the roots of teeth, the mini-implant may at times encroach on the root or the membrane surrounding it (PDL). Damage to the roots or the PDL is usually minimal and can normally repaired by your body. In very rare occasions ankylosis can result with may interfere with further tooth movement.


General considerations:

Please keep in mind that most side effects listed here are rare and usually do not leave significant permanent damage. When compared to the other treatment options, TAD use is generally less painful, less risky, and very well tolerated by patients.
