Signs You Might Need Orthodontic Treatment

The most immediately obvious orthodontic issues are those you can see directly: teeth that overlap each other, teeth that are rotated out of alignment with their neighbours, a noticeable gap between the front teeth (diastema), or upper front teeth that dramatically protrude or sit far behind the lower teeth. These visible misalignments are the scenarios most people associate with needing braces or Invisalign.

• Crowding — teeth overlapping, stacked or rotated due to insufficient arch space.
• Spacing — gaps between teeth, most commonly between the upper front teeth.
• Overjet — upper front teeth protrude significantly forward beyond the lower teeth.
• Open bite — upper and lower front teeth do not touch when biting; a gap exists between them.
• Crossbite — upper teeth sit inside (rather than outside) lower teeth in any part of the arch.

Bite misalignment — called malocclusion — is not always obvious visually. Some patients have teeth that look reasonably straight but whose bite does not function correctly. Signs of bite problems include biting the inside of your cheeks or tongue repeatedly, food that consistently catches or packs between certain teeth, difficulty biting into certain foods, and uneven wear on specific teeth that your dentist points out on x-rays.

An overbite — where the upper front teeth cover too much of the lower front teeth when biting — can cause the lower teeth to bite into the palate (roof of the mouth), causing tissue irritation and wear. An underbite — where the lower jaw extends beyond the upper — affects chewing efficiency and can cause accelerated wear on the lower front teeth. Both are very correctable with orthodontic treatment, often with Invisalign for mild to moderate cases.

Jaw joint discomfort — clicking, popping, locking or pain in the TMJ (temporomandibular joint) — can be caused or worsened by bite misalignment. When the upper and lower teeth do not come together evenly, the jaw muscles and joints must compensate with every bite and swallow, creating chronic strain. Not all TMJ problems are orthodontic in origin, but a significant proportion improve when the bite is corrected. Our TMJ and your bite article covers this connection in detail.

Headaches, particularly those felt at the temples or behind the eyes and worse in the morning, can also be a sign of bite-related muscle clenching. Patients who grind or clench at night — which is often driven or worsened by an uneven bite — may find that orthodontic correction reduces the grinding habit and the headaches associated with it. This is worth discussing at your consultation if you experience morning headaches or jaw stiffness.

Crowded teeth are more than an aesthetic issue — they are a hygiene issue. When teeth overlap, toothbrush bristles cannot reach every surface and floss cannot pass cleanly through the contact points. These uncleaned areas accumulate plaque that causes decay and gum disease over time. Patients with crowded teeth often have more cavities between teeth and more gum inflammation than patients with well-aligned dentition, even when their brushing habits are identical.

If your dentist or hygienist consistently points out areas of plaque accumulation that are difficult to clean because of tooth overlap or crowding, that is a sign that orthodontic correction would improve not just your smile but your long-term periodontal health. Straighter teeth are genuinely healthier teeth, all other factors being equal.

The Canadian Dental Association recommends that children have their first orthodontic assessment by age seven, even if treatment is not needed yet. At this age, the dentist can identify developing problems — narrow arches, crowding that will worsen as permanent teeth erupt, early crossbites — and advise on whether early intervention (phase one treatment) would simplify later comprehensive treatment or whether watchful waiting is appropriate.

Early signs in children that warrant evaluation: persistent thumb or finger sucking beyond age five or six (which can push the front teeth forward), mouth breathing (which affects jaw development), speech difficulties, asymmetrical jaw growth, difficulty chewing, and baby teeth that are slow to fall out or adult teeth that are slow to erupt. None of these guarantee orthodontic treatment is needed, but all are reasons to have an assessment.

Some bite problems are subtle enough that patients do not notice them until a dentist identifies them on x-rays or during a clinical examination. A posterior crossbite, for example, may cause no noticeable symptoms but results in the jaw shifting to one side during biting, creating asymmetric muscle and joint loading over time. A deep bite — significant overbite — may feel normal to the patient while slowly grinding down the lower front teeth.

This is one reason regular dental check-ups are important even for patients who feel fine. Dr. Kadivar checks bite alignment and tooth wear as part of every comprehensive examination. If she identifies a developing orthodontic issue, she will explain what she has found, what the implications are if left unaddressed, and what the treatment options are — without any pressure to proceed immediately.

An orthodontic evaluation at Smile Dental Arts Centre includes a clinical examination of your bite, tooth alignment, jaw joints and gum health, panoramic and periapical x-rays to assess roots and bone, and — for Invisalign candidates — a digital intraoral scan. If orthodontic treatment is recommended, Dr. Kadivar will explain the options (Invisalign, braces or specialist referral for complex cases), expected treatment time and cost.

The evaluation is thorough and unhurried — we do not rush orthodontic assessments because the decision involves a meaningful time and financial commitment. Book an orthodontic evaluation at our Markham clinic to get a clear picture of your current bite health and what — if anything — would benefit from treatment.
