Crooked teeth are a common concern that can impact both the health and appearance of your smile. At Winthrop Orthodontic Centre, orthodontists Dr Gordon Cheung and Dr Naomi Kohan help patients understand the causes of misaligned teeth and offer customised treatment plans to achieve confident, healthy smiles. Whether you’re a parent wondering about your child’s developing teeth or an adult considering braces or aligners, understanding the root causes of crooked teeth is the first step toward a straighter smile.
Orthodontist explains: What causes crooked teeth?
There are several reasons why teeth may become crooked. As experienced orthodontists, Dr Cheung and Dr Kohan explain that these causes can be genetic or environmental and sometimes both.
- Genetics: One of the most common reasons people need an orthodontist is due to inherited traits like jaw size, spacing, or crowding.
- Thumb sucking or prolonged dummy use: Habits during early childhood can impact how the teeth and jaw develop.
- Early loss of baby teeth: Losing baby teeth too early may lead to nearby teeth shifting into the gap, resulting in crooked permanent teeth.
- Jaw misalignment: Overbites, underbites, and crossbites often require intervention from an orthodontist to correct the bite and straighten teeth.
- Poor dental care or trauma: Injuries or poor oral hygiene can lead to teeth shifting out of place over time.
The good news? With the right guidance from an orthodontist, crooked teeth can be treated at any age.
Orthodontist recommendations: Why fixing crooked teeth matters
Some people think crooked teeth are just a cosmetic issue, but orthodontists know there’s much more to it.
- Improved oral hygiene: Straight teeth are easier to brush and floss, reducing your risk of tooth decay and gum disease.
- Better bite and function: Misaligned teeth can lead to jaw strain, headaches, and uneven tooth wear.
- Enhanced confidence: A straight smile can significantly boost self-esteem at any age.
Dr Cheung and Dr Kohan emphasise that seeing an orthodontist early ideally by age 8 allows for early detection of any developing issues, though it’s never too late to seek treatment.
Orthodontist treatments: What is the best course of action?
The best treatment for crooked teeth depends on the severity and cause of the misalignment. At Winthrop Orthodontic Centre, our orthodontists tailor every treatment plan to meet individual needs. Common options include:
- Braces: Traditional braces are highly effective for complex tooth and jaw alignment problems. Your orthodontist will guide you through the process with regular adjustments.
- Clear aligners: Clear aligner systems like Invisalign, offer a discreet way to straighten teeth, and our orthodontists provide expert monitoring to ensure optimal results.
- Expanders or functional appliances: For younger patients, Dr Cheung or Dr Kohan may recommend jaw-expanding appliances to guide proper development.
- Retainers: After active treatment, a custom retainer from your orthodontist helps maintain your beautifully straight smile.
Each treatment begins with a thorough consultation, diagnostic records, and an expert diagnosis from our orthodontists Dr Cheung or Dr Kohan.
Orthodontist insight: When should you seek help?
It’s important to visit an orthodontist as soon as you notice signs of crooked teeth, such as:
- Crowding or overlapping teeth
- Gaps between teeth
- Difficulty biting or chewing
- Jaw pain or clicking sounds
- Mouth breathing or speech issues in children
The sooner you consult with an orthodontist, the more options you’ll have and often, the easier the treatment.
