What Can Aligners Fix?

Updated: Nov 29, 2023

Everyone wants a confident smile. It not only uplifts one's self-esteem but also leaves a lasting impression on others. Traditionally, metal braces were the solution for crooked teeth. However, the advent of aligners has brought a revolution in orthodontics.

They are transparent, removable, and popular for those looking to straighten their teeth discreetly. But what issues can aligners address? This article explores the range of dental problems aligners can fix.

What Can Aligners Fix

Fixing Crowded Teeth With Aligners

When teeth bunch together due to lack of room, we call it crowding. Think of it as trying to fit too many books onto a shelf. Over time, if not addressed, this can lead to many oral health issues. It becomes challenging to brush and floss effectively when teeth overlap.

Consequently, food particles can become trapped, increasing the risk of cavities and gum problems. Aligners, like a helpful hand rearranging those books, can nudge teeth into better positions.

This makes oral hygiene routines more effective. Additionally, well-positioned teeth reduce the chances of dental problems down the line.

Fixing Gaps Between Teeth With Aligners

Spaces between teeth, large or small, are common. While genetics play a role, sometimes a lost tooth or habits from childhood, like thumb sucking, are culprits. Beyond aesthetics, these gaps can invite oral health concerns.

Food particles can lodge in these spaces, leading to potential gum infections or other dental issues. Now, what's the solution? Aligners come into play here. They are tools that help pull the teeth closer, filling those unwanted spaces.

As teeth come together, not only does the appearance improve, but the risks associated with these gaps diminish. It's a dual benefit: a better-looking smile and healthier gums and teeth.

However, it's important to keep your aligners clean as well. You can clean them with simple soap and a soft-bristled brush. Or you can use cleaning sprays like Smilesaver to clean them in a mere 30 seconds!

Fixing Overbite With Aligners

An overbite is a dental condition where the top front teeth extend beyond the bottom ones. While a slight overlap is normal, excessive overbites can cause concerns. For starters, the lower teeth can experience undue wear because they constantly rub against the upper ones.

This wear can lead to sensitivity and other dental problems. Moreover, the gums behind the top teeth can become irritated. But there's good news.

Aligners offer a solution. They function like guides, steering the teeth and jaw to their rightful places. As they work their magic, the extent of the overbite decreases.

Fixing Underbite With Aligners

An underbite describes a situation where the bottom front teeth jut out, overshadowing the top front teeth. This isn't just about appearance; it can have practical implications, too. Chewing and speaking might become a challenge with a pronounced underbite.

Moreover, it can lead to uneven wear on the teeth and may even result in strain on the jaw. Now, what can be done? That's where aligners come into the picture. They are designed to address such dental imbalances.

By strategically applying pressure, aligners can gradually push the bottom teeth backward or coax the upper teeth to move forward.

Fixing Crossbite With Aligners

Crossbite is a dental concern where certain top teeth are positioned behind their corresponding bottom teeth. Instead of neatly lining up, these teeth clash or misalign. When teeth don't align properly, they can grind against each other, leading to premature wear.

This wear can cause tooth sensitivity and increase the risk of cavities. Furthermore, a persistent crossbite can impact gum health and may even contribute to weakening the jawbone over time.

Thankfully, aligners offer a remedy. Designed to adjust tooth positions, they gradually guide the teeth into their proper places.

Fixing Open Bite With Aligners

When someone with an open bite closes their mouth, there's a noticeable space between their upper and lower front teeth. This gap isn't just about looks. It can affect everyday actions like speaking or eating.

Words might sound unclear, and biting into something as simple as a sandwich becomes tricky. The reasons behind an open bite can vary, from genetics to prolonged habits like thumb-sucking.

So, how can this be tackled? Aligners prove to be a practical solution. They are crafted to apply gentle pressure on the teeth, pushing them towards each other. Over time, the gap closes, making everyday actions easier.

Fixing Tooth Rotation With Aligners

Tooth rotation is when a tooth doesn't sit straight but instead twists or turns in its spot. It's like a book on a shelf leaning to one side instead of standing upright. This can disrupt the harmony of the entire dental line-up.

The reasons behind a tooth's rotation can be varied. Some folks might have it due to inherited traits, while others might see it as a result of external pressures, perhaps from an adjacent tooth.

No matter the cause, it's an issue many wish to fix. Here's the good part: aligners are up for the task. These devices work steadily, nudging the rotated tooth bit by bit until it aligns correctly.

Fixing Tooth Protrusion With Aligners

When teeth stick out further than usual, it's termed tooth protrusion. You might have seen this - the teeth, especially the front ones, seem to jut outwards. While many simply know it as "buck teeth," it's more than just a visual concern.

Protruding teeth can be vulnerable to chipping or breaking because they stand out more prominently. Moreover, they might affect the way someone closes their mouth or speaks. The reasons behind it? It could be a childhood habit like thumb-sucking, inherited traits from parents, or even accidents. The silver lining is that aligners can help.

They're designed to apply a consistent, gentle force to move the teeth. Over time, aligners can bring protruding teeth into a more normal position, offering a more aligned smile and reducing potential risks.

Fixing Minor Jaw Alignment Issues With Aligners

Jaw alignment affects how we eat, speak, and even how we look. In some cases, people have minor issues where the upper and lower jaws don't line up perfectly. These aren't just aesthetic concerns. Over time, poor jaw alignment can cause discomfort or wear on the teeth.

How does this happen? It might be due to habits from younger years, genetics, or even minor injuries. Not all jaw issues mean a trip to the surgery room. For those with milder cases, aligners offer a simpler solution.

By moving the teeth gradually, aligners can help line up the jaws better. It's a non-invasive way to enhance facial symmetry and ensure the jaws meet correctly, making everyday actions smoother.


Aligners offer an effective solution to various dental concerns. From crowded teeth to jaw alignment, they provide a non-invasive approach to achieving a better smile. It's not just about looks; aligners can also address issues impacting speech, eating, and oral health.

For many, they're a game-changer, making dental correction more accessible and comfortable. Investing in aligners can mean a healthier, more confident smile for the future.


Q: What dental issues can aligners fix?

A: Aligners can effectively correct various dental issues such as overcrowding, gaps between teeth, bite misalignment, and crooked teeth.

Q: How do aligners work?

A: Aligners work by applying gentle, constant pressure on the teeth to gradually shift them into the desired position. Each set of aligners is worn for a specific period before being replaced with the next set in the series.

Q: Can aligners treat severe orthodontic problems?

A: While aligners can address many orthodontic issues, they may not be suitable for severe cases. It is best to consult with an orthodontist to determine the most appropriate treatment option.
