Conditions We Treat

At Pro Aligners, we specialise in correcting a wide range of orthodontic conditions using advanced, custom-made invisible aligners. Whether your teeth are crowded, spaced, misaligned or have shifted after braces, our expert-led team designs a bespoke treatment plan tailored to your unique smile.

Our clear aligners are comfortable, discreet and highly effective for both adults and teens. Below, you can explore the most common conditions we treat and how aligner therapy can transform your confidence, function and overall oral health.

1. Crowding

Crowding occurs when there isn't enough space for all your teeth to align properly. This can cause overlapping, twisting or teeth sitting out of line.

How ProAligners help:

ProAligners create room by gently expanding the arch and repositioning each tooth for a straighter, cleaner, healthier smile.

2. Spacing

Gaps appear when teeth are too far apart or smaller than normal. They may affect confidence, speech and gum health.

How ProAligners help:

Our clear aligners apply consistent pressure to close gaps and create a uniform, balanced smile.

3. Overbite

An overbite is when the upper front teeth overlap the lower front teeth more than normal.

How ProAligners help:

We improve vertical alignment to enhance bite function, facial aesthetics and long-term tooth stability.

4. Underbite

An underbite occurs when the lower front teeth extend forward beyond the upper front teeth.

How ProAligners help:

ProAligners reposition the bite relationship and reduce the prominence of the lower teeth for improved balance and function.

5. Open Bite

With an open bite, the upper and lower front teeth do not touch when the mouth is closed, leaving a visible gap.

How ProAligners help:

Clear aligners guide the front teeth into proper contact, improving chewing efficiency, speech and aesthetics.

6. Crossbite

A crossbite happens when one or more upper teeth bite inside the lower teeth, instead of outside.

How ProAligners help:

ProAligners gently correct arch width and tooth position to prevent uneven wear, gum recession and jaw imbalance.

7. Rotated Teeth

Rotated teeth twist out of alignment due to crowding, genetics or bite issues.

How ProAligners help:

Our aligners apply targeted rotational force to bring each tooth back into its ideal position with precision and comfort.

8. Impacted Teeth

Impacted teeth are blocked from erupting fully through the gum.

How ProAligners help:

In suitable cases, aligners create the space required to support the tooth's natural eruption and alignment.

9. Overjet

Overjet refers to the forward protrusion of upper front teeth ('buck teeth').

How ProAligners help:

ProAligners retract and align the upper teeth to improve facial profile, bite comfort and smile harmony.

10. Teeth Shifting After Braces

Teeth often move again after braces—especially when retainers aren't worn (Orthodontic Relapse).

How ProAligners help:

Our treatment quickly corrects relapse, realigns shifting teeth and includes retainers to maintain your results long-term.

11. Bite Problems

Bite problems refer to misalignment between the upper and lower teeth when the mouth closes, commonly known as malocclusion.

How ProAligners help:

A structured orthodontic assessment can determine whether bite alignment requires treatment and which correction options may be suitable.

12. Crooked Teeth

Crooked teeth are misaligned, rotated or unevenly positioned within the dental arch, affecting smile balance and hygiene access.

How ProAligners help:

An orthodontic assessment can evaluate the degree of misalignment and help determine whether treatment such as clear aligners may be appropriate.

13. Crowded Teeth

Crowded teeth occur when there is insufficient space within the dental arch, causing teeth to overlap, rotate or sit unevenly.

How ProAligners help:

An orthodontic assessment can evaluate the degree of crowding and help determine whether treatment may improve alignment and hygiene access.

14. Front Teeth Gap (Diastema)

A front teeth gap, or diastema, is a visible space between the upper front teeth that may be cosmetic or related to alignment.

How ProAligners help:

An orthodontic assessment can evaluate the gap and determine whether treatment such as clear aligners may help close the spacing.

15. Gapped Teeth

Gapped teeth refer to visible spaces between two or more teeth within the dental arch, which may affect oral hygiene or bite balance.

How ProAligners help:

An orthodontic assessment can evaluate the spacing and determine whether treatment may help close gaps and improve alignment.

16. Overlapping Teeth

Overlapping teeth occur when one tooth partially covers or sits in front of another, which may affect oral hygiene and bite balance.

How ProAligners help:

An orthodontic assessment can evaluate the degree of overlap and determine whether treatment such as clear aligners may help improve alignment.

17. Spacing Between Teeth

Spacing between teeth refers to visible gaps or spaces that occur between two or more teeth within the dental arch, which may affect oral hygiene or bite balance.

How ProAligners help:

An orthodontic assessment can evaluate the spacing and determine whether treatment such as clear aligners may help close gaps and improve alignment.

18. Adult Teeth Alignment Problems

Adult teeth alignment problems refer to situations where permanent teeth are not positioned evenly within the dental arches, involving crowding, spacing, rotation or bite differences.

How ProAligners help:

An orthodontic assessment can evaluate adult teeth misalignment and help determine whether treatment such as clear aligners may be appropriate.

19. Asymmetrical Smile

An asymmetrical smile occurs when one side of the smile appears different from the other, involving differences in tooth alignment, tooth height, or dental arch position.

How ProAligners help:

An orthodontic assessment can evaluate smile asymmetry and help determine whether treatment such as clear aligners may improve alignment and smile balance.

20. Bite Misalignment

Bite misalignment occurs when the upper and lower teeth do not meet in their typical positions when the mouth closes, often referred to as malocclusion.

How ProAligners help:

An orthodontic assessment can evaluate bite alignment and help determine whether treatment such as clear aligners may improve how the teeth meet.

21. Buck Teeth

Buck teeth is a commonly used term to describe upper front teeth that extend noticeably forward, often associated with increased overjet.

How ProAligners help:

An orthodontic assessment can evaluate the degree of tooth projection and help determine whether treatment such as clear aligners may improve alignment.

22. Deep Bite

A deep bite refers to excessive vertical overlap of the upper front teeth over the lower front teeth, a common form of malocclusion.

How ProAligners help:

An orthodontic assessment can evaluate the degree of vertical overlap and help determine whether treatment such as clear aligners may improve bite alignment.

23. Irregular Smile Line

An irregular smile line refers to uneven positioning of teeth when smiling, where teeth may appear at different heights or angles.

How ProAligners help:

An orthodontic assessment can evaluate smile line irregularity and help determine whether treatment such as clear aligners may improve alignment and symmetry.

24. Jaw Alignment Issues

Jaw alignment issues occur when the upper and lower jaws do not align in their typical relationship, which may influence how the teeth meet during biting.

How ProAligners help:

An orthodontic assessment can evaluate bite relationships and help determine whether treatment such as clear aligners may improve jaw and bite alignment.

25. Midline Shift

A midline shift occurs when the centre line between the upper and lower front teeth does not align, which may affect facial symmetry and bite function.

How ProAligners help:

An orthodontic assessment can evaluate midline discrepancies and help determine whether treatment such as clear aligners may correct alignment and improve symmetry.

26. Misaligned Teeth

Misaligned teeth refer to teeth that are not positioned correctly within the dental arch, appearing crooked, rotated, crowded or spaced unevenly.

How ProAligners help:

An orthodontic assessment can evaluate tooth alignment and help determine whether treatment such as clear aligners may improve positioning and overall dental alignment.

27. Narrow Dental Arch

A narrow dental arch refers to a dental arch that appears smaller or more constricted than typical, which may reduce the available space for teeth to align evenly.

How ProAligners help:

An orthodontic assessment can evaluate arch width and help determine whether treatment such as clear aligners may improve alignment and create space within the arch.

28. Protruding Teeth

Protruding teeth refer to teeth that extend further forward than typical alignment within the dental arch, most commonly affecting the upper front teeth.

How ProAligners help:

An orthodontic assessment can evaluate tooth position and overjet and help determine whether treatment such as clear aligners may reduce protrusion and improve alignment.

29. Smile Alignment

Smile alignment refers to how teeth appear positioned when smiling. Differences in spacing, crowding or rotation may affect the overall appearance and balance of the smile.

How ProAligners help:

An orthodontic assessment can evaluate tooth positioning and smile balance and help determine whether treatment such as clear aligners may improve alignment.

30. Teen Teeth Alignment Problems

Teen teeth alignment problems refer to situations where permanent teeth in adolescents are not positioned evenly within the dental arches during this key developmental stage.

How ProAligners help:

An orthodontic assessment can evaluate teen tooth alignment and help determine whether treatment such as clear aligners may be appropriate during this stage of dental development.

31. Teeth Biting Inside Incorrectly

Teeth biting inside incorrectly refers to a crossbite, where some upper teeth sit inside the lower teeth when biting down, reversing the typical bite relationship.

How ProAligners help:

An orthodontic assessment can evaluate crossbite alignment and help determine whether treatment such as clear aligners may improve bite balance and tooth positioning.

32. Teeth Crowding in Lower Jaw

Lower teeth crowding occurs when there is insufficient space within the lower dental arch for teeth to align properly, causing teeth to overlap, rotate or sit at different angles.

How ProAligners help:

An orthodontic assessment can evaluate lower arch crowding and help determine whether treatment such as clear aligners may improve tooth alignment and spacing.

33. Teeth Crowding in Upper Jaw

Upper teeth crowding occurs when there is insufficient space in the upper dental arch for teeth to align properly, causing teeth to overlap, rotate or appear misaligned.

How ProAligners help:

An orthodontic assessment can evaluate upper arch crowding and help determine whether treatment such as clear aligners may improve tooth alignment and spacing.

34. Teeth Relapse After Orthodontic Treatment

Orthodontic relapse refers to teeth gradually shifting back toward their previous position after orthodontic treatment, which may occur after braces or clear aligners.

How ProAligners help:

An orthodontic assessment can evaluate the degree of relapse and help determine whether further treatment such as clear aligners may restore alignment.

35. Teeth Sticking Out

Teeth sticking out refers to front teeth that project forward more than usual, often associated with increased horizontal overlap between the upper and lower teeth.

How ProAligners help:

An orthodontic assessment can evaluate the degree of protrusion and help determine whether treatment such as clear aligners may improve alignment and reduce forward projection.

36. Tilted Teeth

Tilted teeth refer to teeth that lean inward or outward instead of sitting upright within the dental arch, which may affect a single tooth or multiple teeth.

How ProAligners help:

An orthodontic assessment can evaluate tooth angulation and help determine whether treatment such as clear aligners may improve alignment and upright positioning.

37. Uneven Spacing Between Teeth

Uneven spacing between teeth refers to irregular gaps that appear between certain teeth while others sit closer together, creating an inconsistent pattern of spaces across the dental arch.

How ProAligners help:

An orthodontic assessment can evaluate the pattern and distribution of spacing and help determine whether treatment such as clear aligners may improve tooth positioning and gap closure.

38. Uneven Teeth Alignment

Uneven teeth alignment refers to teeth that do not sit evenly within the dental arch, appearing slightly crooked, rotated, crowded or positioned at different angles.

How ProAligners help:

An orthodontic assessment can evaluate the pattern and extent of alignment irregularity and help determine whether treatment such as clear aligners may improve tooth positioning.
