Why straight teeth are about more than how they look

Teeth you can actually clean

The surfaces that decay and the gum margins that become inflamed are the ones a toothbrush cannot reach. Where teeth overlap, twist or sit behind one another, they create ledges and pockets that trap plaque no matter how diligent you are. We see this at every hygienist appointment: the crowded lower front teeth are the ones with the tartar, and the overlapped upper canine is the one with the early decay on its hidden side.

Once the teeth sit in an even arch, the brush and floss do what they were designed to do. There is nowhere for plaque to hide, and the daily routine takes less time and effort for a better result. This sounds minor until you consider the arithmetic. Two minutes twice a day, for decades, on surfaces that are now reachable, adds up to a very large reduction in the lifetime risk of fillings and gum treatment.

Gums that are not fighting plaque all day

Gum disease begins where plaque sits undisturbed against the gum, and crowding provides exactly that. The early sign is bleeding when you brush. Left alone, the inflammation moves deeper, the bone that holds the tooth begins to recede, and the tooth loosens. Gum disease takes more adult teeth than almost anything else, and it gives little warning until it is advanced.

Aligning teeth does not cure gum disease, and we treat any active disease before moving a tooth. What alignment does is remove the hiding places, so that the hygienist's work and your own holds. For people who have already lost some bone, straightening can also redistribute the load so that no single tooth is taking more than its share. The gums, for their part, tend to settle into an even scalloped line that is easier to keep and looks healthier too.

Less wear on the teeth themselves

Teeth are designed to meet in a particular way, with the chewing forces spread across many contacts at once. When one tooth sits proud or tilted, it takes the brunt of every bite and every grind in the night. Over years this shows as a chipped incisal edge, a flattened canine, or a crack running through a back tooth that eventually needs a crown. Because every appointment here starts with a scan, this wear can be compared from one visit to the next rather than guessed at.

Much of the tooth wear we treat at Sardinia House has a bite problem somewhere in its history. Bringing the teeth into a balanced position is often the first stage of a rebuild, because there is little point restoring a worn edge if the opposing tooth is going to chip it again. In milder cases, alignment alone, with a night guard for protection, stops the damage before any restoration is needed.

A bite and a jaw that feel comfortable

A bite that does not meet evenly makes the jaw muscles work harder to find a stable position, and some people feel that as tightness in the cheeks, tension at the temples or a jaw that clicks on opening. Not every ache has a dental cause, and we are careful not to promise relief from orthodontics alone. But where the bite is clearly part of the picture, aligning the teeth so they meet together can be expected to take some of the strain off the joints and muscles.

Chewing is also simply more efficient when the teeth fit. Food is broken down by many small contacts rather than a few large ones, and the front teeth can cut without being overloaded. People who have corrected a deep bite or an open bite usually mention this in passing, a few months in, as something they had not expected to notice.

Speech, and the things nobody mentions

The tongue and lips shape sounds against the teeth, and certain gaps or protrusions produce a whistle or lisp that the person has lived with so long they no longer hear it. Closing a space between the front teeth or bringing them back into the arch can tidy this up. It is never the main reason to seek treatment, but it is a welcome side effect that comes up more often than you might think.

If you are weighing up orthodontics as an adult, the question to ask is not whether your teeth are ugly. Most are not. The question is whether they are costing you something, in cleaning time, in gum health, in wear or in comfort. An iTero™ scan at your first visit will show you the answer on screen, and a written plan, with the fee set out, lets you decide at your own pace.
