Orthodontic Mini-Screws (TADs): What They Are and Why They Are Used

Temporary anchorage devices, often called TADs or mini-screws, can help orthodontists move certain teeth more predictably without relying only on other teeth for support.

What is a TAD?

A TAD is a small temporary anchor placed in the gum and supporting bone to help control tooth movement. It is not the same thing as a dental implant meant to replace a missing tooth.

Because it acts as a fixed anchor point, it can make certain movements easier or more efficient.

Why do orthodontists use them?

They may be used to help close spaces, intrude or extrude teeth, retract front teeth, reduce unwanted movement of neighbouring teeth or avoid more cumbersome appliances.

For adults, TADs can be especially useful when anchorage demands are high and compliance-dependent alternatives are less ideal.

How are they placed and removed?

Placement is usually done under local anaesthetic in the practice. Removal is typically simple and much quicker than people imagine once the device is no longer needed.

Because TADs are temporary, they are taken out when that stage of movement is complete.

Does a TAD hurt?

You may feel pressure during placement and some soreness afterward, but many adults find the procedure easier than they expected. The surrounding cheek or tongue may need a short adjustment period.

If a TAD becomes repeatedly sore, mobile or difficult to clean, it should be reviewed.

How do you keep it clean?

Meticulous hygiene matters because plaque around the screw head can irritate the tissue and increase failure risk. Your orthodontist may suggest careful brushing, rinsing or other site-specific advice.

Do not poke, twist or try to tighten it yourself.

When should you contact the orthodontist?

Call if the TAD becomes loose, starts rubbing badly, develops persistent swelling or seems to disappear under inflamed tissue. Many issues are manageable when caught early.
