Orthodontic treatment moves teeth through bone into positions where they meet correctly, can be cleaned, and share the load of chewing evenly. Straight front teeth are the visible result of that, not the purpose of it.
This distinction explains a great deal about how treatment is planned, why the middle of it feels slow, and why a case that looks finished to the patient often is not.
How a tooth moves through bone at all
A tooth is not fixed in the jaw like a nail in wood. It is suspended in its socket by the periodontal ligament, a layer of fibres a fraction of a millimetre thick connecting root to bone, richly supplied with blood and cells.
When steady pressure is applied, the ligament is compressed on one side and stretched on the other. The compressed side triggers cells that resorb bone; the stretched side triggers cells that lay new bone down. The tooth moves into the space created behind it, and bone fills in where it came from. The jaw rebuilds itself around the tooth as it goes.
Two consequences follow. First, the force has to be light and continuous rather than heavy: too much pressure cuts off the blood supply in the ligament and stalls the process instead of speeding it up, while risking damage to the root. Second, the whole thing runs at a biological pace that cannot be substantially hurried, which is why treatment is measured in months — see how long orthodontic treatment takes.
It also explains retention. Once active movement stops, the bone is still consolidating and the ligament fibres are still stretched. Without something holding the new position, they pull the teeth back — see retainers.
What a working bite has to do
Aligning teeth within an arch is one problem. Making the two arches meet properly is a different one, and it is where most of the clinical value lies.
- The back teeth take the load. They should meet evenly, so that force is shared rather than concentrated on a few teeth.
- The front teeth do the cutting, and should overlap enough to do it without the lower edges striking the palate.
- The teeth should separate correctly during sideways movement, so that chewing does not grind the back teeth against each other.
- Nothing should be left to bear a load it is not shaped for.
When any of this is wrong, the consequences are cumulative rather than sudden: uneven wear, chipping, teeth that are painful to bite on, gum recession on overloaded teeth, and restorations that keep failing on one side.
What orthodontics can correct
- Crowding, by creating space — through expansion, by slight reshaping between teeth, or by extraction where there is genuinely not enough room.
- Spacing, by closing gaps.
- Rotations, turning a tooth back into line.
- Overjet and overbite, the horizontal and vertical relationships of the front teeth.
- Crossbites, where upper teeth bite inside the lower ones.
- Open bites, where teeth that should meet do not.
- Impacted teeth, guiding a tooth that has failed to erupt into position.
- Tooth position before restorative work — uprighting a tipped tooth, or opening space for a replacement.
What it cannot do on its own
Being clear about limits is more useful than a longer list of capabilities.
It does not change tooth colour. That is whitening or other cosmetic treatment.
It does not change the shape of a tooth. A chipped or worn edge still needs repairing afterwards — see fixing a chipped or worn front tooth.
It cannot substantially change the jaws in an adult. In a growing child, growth can be influenced. In an adult, a significant skeletal discrepancy can be camouflaged by tooth position or corrected surgically in combination with orthodontics, but not moved by braces alone.
It does not treat gum disease — and it makes untreated gum disease worse. Gum health comes first, always. See our gum and periodontal care page.
It does not reliably cure jaw joint pain. Bite and joint symptoms are related in complex ways, and orthodontics is sometimes part of the answer and sometimes not. Be cautious of treatment sold primarily on that promise.
Aligning versus correcting
Short cosmetic treatment that straightens the visible front teeth is a real option and suits some people well. What it does not do is address the bite. If the way your teeth meet is what pushed them out of line, straightening the fronts without correcting it produces a result that looks right and does not hold.
Ask which you are being offered. Both are legitimate; they are not the same product.
Frequently asked questions
Does moving teeth damage them?
Some shortening of the root occurs to a small degree in many patients and is usually of no consequence. It is monitored radiographically, and light forces reduce the risk.
Why do teeth feel loose during treatment?
Because the ligament widens while the tooth is moving. They firm up again once movement stops and the bone consolidates.
Can teeth be moved too fast?
Yes, and it is counterproductive. Excessive force stalls movement and risks root damage. Be sceptical of dramatic speed claims.
Will my face change?
Lip support can change where the front teeth are moved substantially, and this should be discussed at planning. Orthodontics does not reshape the jaws in an adult.
Find out what your case actually needs
Whether your case is about alignment, the bite, or both is what an assessment establishes. See our orthodontics page and do I need braces?
