Getting your bite right after All-on-6

What “your bite” means

Dentists use the word occlusion for how your upper and lower teeth come together: when you close, when you chew, and when you slide your jaw sideways or forwards. A good bite spreads force evenly over many teeth, lets your jaw close in a comfortable position, and guides the teeth smoothly when you move your jaw.

With natural teeth, small problems in the bite are partly absorbed by the ligament around each tooth, which allows a tiny amount of movement. Implants are fused to bone without a ligament, so there is less give. A contact that hits slightly too hard on an implant bridge is felt less, and the force goes straight into the bridge, screws and implants. See how All-on-6 teeth feel.

Why the bite changes after fitting

• Records are never perfect. The bridge is made from scans or impressions and bite records; the real test is in your mouth.
• Swelling and healing after surgery can change how you close in the first weeks.
• Muscles adapt to a new bite height, especially after years of a collapsed bite with dentures. See how All-on-6 changes your face.
• The final bridge differs from the temporary in material and shape.
• The opposing teeth may change: a natural tooth moves, a denture wears, or the other jaw is treated later.

How the bite is checked and adjusted

1. MarkingThin coloured articulating paper is placed between the teeth. You bite, tap and slide your jaw; the paper leaves marks where the teeth touch.
2. Reading the marksThe dentist looks for contacts that are much heavier than others, contacts on only one side, or teeth that hit when you slide sideways.
3. AdjustingThe high spots are smoothed with fine instruments, then polished. With acrylic it is quick; with zirconia, the surface is polished carefully afterwards to keep it smooth.
4. Re-checkingYou bite again until contacts are even and comfortable.

It usually takes a few minutes and needs no anaesthetic. Expect a check soon after the temporary bridge is fitted, and again after the final bridge, once you have used it for a short while.

Why a balanced bite protects your All-on-6

A 2025 systematic review examined how occlusal overload, too much force on implants, relates to the health of the tissues around them, and research on bruxism links heavy forces to mechanical problems with implant restorations. Uneven contacts are a common cause of:

• Chipping of porcelain or teeth on the bridge. A 2017 review found minor chipping in about 15% of zirconia full-arch bridges.
• Screws loosening or breaking. See broken or loose bridge.
• Wear of acrylic teeth or opposing natural teeth.
• Jaw muscle and joint pain. The NHS notes that jaw pain can lead to temporomandibular disorder.

Signs your bite needs attention

• One tooth or one side hits first when you close.
• You find yourself chewing only on one side.
• Your jaw aches after meals or on waking.
• You hear or feel a click from the bridge when you bite.
• A new chip appears, or the same tooth keeps chipping.
• You keep biting your cheek or tongue after the first few weeks.

Any of these is a reason to book a check, even if your next routine visit is months away.

Grinding and the bite

If you grind or clench, the bite matters even more, because those forces are far greater than normal chewing. Dentists often aim for a flatter, smoother bite for grinders and recommend a night guard made for the final bridge. Read teeth grinding and All-on-6.

When both jaws are new

With full-mouth All-on-6, both bridges are designed together, giving the dentist complete control over the bite. It also means there is no natural reference left, so careful checking matters. With one jaw treated, the bridge must work with whatever is opposite: natural teeth, crowns or a denture. Changes to the opposite jaw later, such as a new denture, can alter the bite and may need the bridge to be checked again.

Over the years

Bites change slowly. Acrylic wears, opposing teeth move, and your jaw muscles change with age. Maintenance visits include a bite check for this reason. If the bite has worn down significantly, teeth on the bridge can be rebuilt or replaced. See maintenance visits and how long All-on-6 lasts.

Questions to ask

• When will my bite be checked after each bridge is fitted?
• What should I do if one side hits first?
• Do I need a night guard?
• How will my bite be checked if I am treated abroad and go home soon after?

The bite on the temporary bridge

The temporary bridge has two jobs where the bite is concerned. While the implants heal, it is usually designed to keep heavy forces off the implants, for example with lighter contacts and sometimes fewer back teeth. It is also a test. How you close, chew and speak on the temporary teeth gives the dentist information for designing the final bridge. If something about the bite on the temporary bridge bothers you, say so: it is much easier to change the design before the final bridge is made than after.

Bite height and comfort

Many people who have worn dentures for years have a bite that has slowly collapsed: the jaws close closer together than they used to. All-on-6 often restores some height. That can improve appearance and chewing, but it also means the jaw muscles have to work at a new length. Some aching in the first weeks is common and usually settles. A bite opened too far can feel tiring and make speech harder; one left too closed can look aged and crowd the tongue. Finding the right height is part of the planning, and the temporary bridge is used to check it.

Sideways movements

Your bite is not only about closing straight. When you chew, your jaw also moves slightly sideways and forwards. In a well-designed bite, these movements are guided smoothly, usually by the front teeth or canines, so that the back teeth separate and are not dragged across each other. If the back teeth rub or catch when you move your jaw sideways, the forces on the implants and bridge increase. The dentist checks these movements with marking paper as well as simple closing.

If you are treated abroad

If you travel for All-on-6, you may go home soon after the final bridge is fitted. Ask how the bite will be checked once you have used the bridge for a few days, and who will do any later adjustments. A UK dentist can usually make small bite adjustments to a bridge; bring your records. If you notice a high spot after you get home, don't wait for months.

Your part

You are the best judge of how your bite feels. Notice whether you chew evenly on both sides, whether anything hits first, and whether your jaw feels tired. Tell your dentist in plain words; they rely on your description as much as on the marking paper.

Common questions

Why does my bite need adjusting after the bridge is fitted?

The bridge is designed from records, but you only find out exactly how it meets when you use it. Swelling, muscle changes and getting used to new teeth all affect the bite in the first weeks.

Does bite adjustment hurt?

No. The dentist marks the contacts with thin coloured paper and smooths or reshapes the bridge surface. No anaesthetic is usually needed.

How many adjustments are normal?

One or two checks after each bridge is fitted is common. Persistent problems after that should be investigated.

Can a bad bite damage implants?

Excessive or uneven force is linked to mechanical problems such as chipping and screw loosening, and some research links overload to bone loss around implants. A balanced bite helps protect the whole system.

My jaw aches since the bridge was fitted. Is that the bite?

It may be. A new bite height, muscles adapting or clenching can all cause aching. Mention it to your dentist, especially if it lasts more than a couple of weeks.
