- Thurman Orthodontics in Bakersfield offers personalized, advanced care for lasting smiles.
Overlapping teeth often called crowded or misaligned teeth are one of the most common orthodontic concerns among children, teens, and adults. This condition occurs when there isn’t enough space in the jaw for teeth to sit in their proper positions, leading to crowding, twisting, or one tooth partially covering another. While many people view overlapping teeth as a cosmetic issue, it can also affect oral health, bite function, and long-term comfort. Understanding why overlapping occurs and how it can be treated is the first step toward achieving a healthier, more confident smile.
What are Overlapping Teeth?
Overlapping teeth is a condition where one or more teeth partially cover the teeth next to them rather than aligning evenly. This condition can develop in the upper or lower jaw and range from slight overlapping and crowding to a significant overlap. Though it might seem like a cosmetic issue, if it is left untreated, it can cause functional problems over time.
What Causes Overlapping Teeth?
Tooth overlap can occur due to various factors involving genetics, oral habits, or jaw development. Understanding the cause can help you decide which is the best treatment plan in your case.
Genetic Factors:
-
Misalignment
Your jaw size and tooth alignment are inherited traits. If you have tooth misalignment running in the family, there is a very high chance that you will develop crooked teeth as well.
-
Difference in Jaw and Tooth Size
If your jaw size is smaller than your teeth size, your teeth will not have enough space to align properly, and this causes them to crowd or overlap.
Childhood Habits & Early Development:
-
Thumb-Sucking and Using the Pacifier
If you, as a child, had the habit of sucking your thumb or your children have the same habit during their early childhood, it puts extra pressure on the teeth, which gradually shifts them from their original position and can cause overlapping. This can also happen when there is prolonged use of pacifiers.
-
Early Loss of Baby Teeth
If a child loses their baby teeth too soon, it causes the teeth near them to drift. This leaves very little room for the permanent teeth to emerge properly and causes crowding.
-
Tongue Thrusting
If a person has a habit of pushing the tongue against the front teeth while they swallow their food, it causes the teeth to move forward and can be a cause of overlapping.
Other Causes:
-
Missing Teeth
If there is a gap from missing teeth, the teeth nearby can tilt or shift into the space, which can be a cause of crowding.
-
Impacted Teeth
If a tooth, like the wisdom tooth, does not emerge properly, it can cause pressure on the teeth next to it and cause overlapping and affect alignment.
-
Poor Oral Care
Being careless about your oral hygiene and leaving cavities untreated alters your bite balance and causes gradual misalignment.
-
Periodontal Disease
When a person suffers from any gum disease, it weakens the bones that support the teeth. This allows them to shift and crowd together and overlap.
-
Less Jaw Space
If your jaw is naturally narrow and there is a high chance of developing tooth crowding, since there isn’t enough room for the teeth to emerge.
-
Injuries
An injury to the jaw can cause the teeth to shift from their original place and cause misalignment and overlapping.
-
Poorly Fitted Dental Work
When crowns and fillings are not placed properly, they can also affect the alignment of the teeth gradually.
Why Overlapping Teeth Should Be Treated?
Even a small overlap can affect how your teeth look and function. If you get these concerns attended to early, you can prevent complications such as:
Health Issues:
-
Gum Problems and Decay
When teeth overlap, it causes dirt to accumulate in gaps where your toothbrush cannot reach. It causes plaque buildup, which is hard to clean in certain areas, and increases the risk of gum disease and cavities.
-
Bite Irregularities
When the teeth are not evenly aligned, it can interfere with chewing, which can lead to jaw strain or discomfort.
-
Jaw Pain and Headaches
The strain caused on your jaw when you chew with uneven teeth can lead to headaches over a period of time and cause other Temporomandibular disorders(TMJ disorders), which are a group of more than 30 conditions that cause pain and dysfunction in the jaw joint and muscles that control jaw movement.
-
Tooth Grinding
Uneven teeth can cause clenching and grinding of teeth, which leads to gum recession and tooth damage.
-
Excessive Tooth Wear
Uneven distribution of pressure on the teeth when they are not aligned properly can erode enamel faster than usual.
Cosmetic and Self-Confidence Issues:
-
Smile Aesthetics
Crowding makes your teeth look crooked, which affects the appearance of your smile.
-
Self-Esteem Impact
Many people feel self-conscious about crooked teeth and hesitate to smile freely.
Other Concerns:
-
Speech Issues
In severe cases, overlapping front teeth may interfere with tongue placement during speech. This can cause people to lisp and not be able to pronounce certain words correctly.
How to Fix Overlapping Teeth?
There are a number of ways to fix crowding and overlapping of teeth. Thurman Orthodontics provides several solutions tailored to each patient’s needs and preferences.
-
Braces
Braces are one of the most reliable methods to realign teeth.
- Traditional Braces: These are durable metal brackets and wires that gently guide teeth into an ideal position.
- Ceramic Braces: These are tooth-colored brackets that blend with natural enamel for a natural look.
- Lingual Braces: These braces are attached behind the teeth to give you an invisible correction.

-
Invisalign
Invisalign uses clear, removable trays to correct misalignment comfortably and discreetly. It’s very effective for mild to moderate overlapping and is a popular choice among adults and teens.
-
Veneers
Veneers are thin porcelain shells that can mask minor overlaps to improve the appearance without orthodontic movement.
-
Dental Bonding
Composite material is applied in this procedure to reshape teeth and improve symmetry in minor cases of overlapping.
-
Tooth Extraction
In severe cases of tooth crowding, removing one or more teeth creates the space needed for alignment.
-
Jaw Surgery
When overlap is caused because of improper bone structure, surgery combined with orthodontic treatment can correct the jaw’s structure for proper function and look.
What are the Benefits of Correcting Overlapping Teeth?
Fixing tooth crowding isn’t only about how you look; it’s about health, comfort, and confidence. Here are the advantages:
- Easier daily cleaning and better oral hygiene
- Reduced risk of gum inflammation and decay
- Balanced bite for efficient chewing
- Decreased jaw strain and clenching
- Improved smile appearance and confidence
- Proper speech
How Long Does Treatment Take?
The duration of treatment for dental crowding depends on several factors, including the severity of misalignment, the type of correction required, and the method chosen. On average, most patients can expect their treatment to last between 12 and 24 months.
However, this timeline isn’t the same for everyone. Mild cases of teeth overlap may be corrected in as little as 6 to 12 months, especially with solutions like Invisalign for minor crowding. More complex cases involving bite correction or severe overlap may take closer to two years, particularly when braces or jaw alignment procedures are needed.
Other factors that can affect this timeline are:
- Age
- Consistency
- The appliance chosen
- Oral habits
Can Overlapping Teeth Be Prevented?
Although genetics can’t be avoided, you can lower the risk of overlapping by following some preventive habits, like:
- Encourage regular dental visits and early orthodontic checkups.
- Discourage thumb-sucking and pacifier use after age 2–3.
- Replace lost baby teeth promptly with space maintainers.
- Schedule an orthodontic evaluation by age 7 to detect potential crowding early.
If you notice overlapping teeth or discomfort in your bite, professional care can make all the difference. At Thurman Orthodontics, Dr. Brian Thurman and his team use advanced technology and a patient-centered approach to deliver excellent results through Invisalign and braces.

-
How Can I Maintain Hygiene with Tooth Crowding?
