Adult With Baby Teeth: Causes, Treatment, and When to See a Dentist

It is not uncommon for adults to retain one or more primary teeth. While many people go years without realizing they have them, these teeth require professional monitoring. If you are an adult with baby teeth, the primary question is whether the tooth is healthy and functional or if it requires intervention. As a dental professional, you can find resources, products, and information to give your patients a healthier future regarding these cases.

What Causes Retained Primary Teeth?

Children typically have 20 primary teeth that begin erupting around 6 months of age, eventually replaced by 32 permanent teeth by age 21. When this transition fails, it is often due to missing teeth congenital conditions or other developmental factors.

• Tooth Agenesis: The permanent successor fails to develop, which is the most common cause of retained primary teeth.
• Impaction: The permanent tooth is present but physically blocked from breaking the gumline.
• Developmental Factors: Childhood injuries or infections that disrupted the natural eruption process.

Is Extraction Necessary?

Not necessarily. If an over retained deciduous teeth case is well-aligned and maintains the mouth’s bone and tissue structure, it may not require treatment. A systematic review in the European Journal of Prosthodontics and Restorative Dentistry (EJPRD) indicates that these teeth can have reasonable survival for two decades. However, dentists monitor for specific complications, including:

• Root Resorption: The breakdown of the tooth root, which can lead to premature mobility.
• Infraocclusion: The tooth sits below the level of adjacent teeth, which may cause neighboring teeth to tilt or shift.
• Dental Caries: Increased susceptibility to decay due to differences in enamel thickness compared to permanent teeth.
• Periodontal Bone Loss: Deterioration of the supporting bone structure.

Treatment and Management

If a tooth is failing or causing issues, your dentist may recommend intervention. According to the Open Dentistry Journal (VOLUME 13, PAGE 190, FULLTEXT), if a permanent tooth is impacted, the primary tooth should be extracted to allow for spontaneous eruption of the permanent successor. Once extracted, dental implants are considered a highly successful long-term replacement. For short-to-medium-term needs, resin-bonded bridgework is a potential option.

Frequently Asked Questions

Should I be worried if I have a baby tooth?

Not automatically. Many adults live with retained primary teeth without issues. A dentist can determine if your tooth is healthy via clinical examination and X-rays.

Can a baby tooth last a lifetime?

In some cases, yes. If the tooth is structurally sound and the surrounding bone is healthy, it can provide many years of service.

When is extraction required?

Extraction is typically recommended if the tooth is causing pain, is severely decayed, is an ankylosed baby tooth, or if it is preventing a permanent tooth from erupting properly. Red flags include sudden mobility, persistent gum inflammation, or visible shifting of adjacent teeth.

Who should I consult for treatment?

Always consult your dentist or an orthodontist. They are the best professionals to evaluate your specific case and determine if intervention is necessary.
