Clinical Crown vs. Anatomical Crown: Key Differences Explained

A clinical crown is the portion of your tooth visible above the gumline, whereas an anatomic crown is the entire top section of the tooth covered in enamel, including parts hidden by your gums. Because your gumline can shift due to recession or genetics, your clinical crown size is dynamic, while your anatomical crown remains constant.

Defining the Terms

• Clinical Crown: The visible region of your teeth not covered by your gums, including your visible enamel-covered anatomic crowns and visible root.
• Anatomic Crown: The top portion of your teeth is covered in enamel, including parts covered by your gums.
• Artificial Crown: A restoration in the form of a cap that replaces most of your entire clinical crown.

Factors Influencing Your Clinical Crown

The appearance of your clinical crown is influenced by several factors:

• Your natural, inherited gumline: Determines the baseline visibility of your teeth.
• Gum recession from improper dental care: Can expose the root, which is protected by cementum rather than enamel, making it more vulnerable. Clinical note: Cementum is significantly softer than enamel, increasing the risk of root caries (decay) when exposed.
• Proportions: The size of your teeth relative to your jaw, facial bones, lips, and teeth.

Common Clinical Crown Procedures

If you are unhappy with your smile or require restorative work, your dental professional may recommend dental crown lengthening or other procedures to improve your oral health.

• Crown lengthening: If your gum covers an uncommon amount of your clinical crown, it can lead to unhappiness with your appearance or make it difficult to place restorations. This procedure exposes more of the tooth to provide a brighter smile.
• Teeth contouring: If your teeth appear long or irregular, this procedure assists with your appearance, bite, or alignment.
• Gingivectomy: The surgical removal of excess gum tissue.
• Gingival flap surgery: Used for advanced gum disease patients when other techniques have been ineffective; your dental professional cleans the roots of your teeth and repairs bone tissue.
• Surgical extrusion: A procedure to treat damaged teeth by repositioning them to help promote the growth of a healthy supporting structure.

Recovery and Aftercare

Recovery time varies based on the invasiveness of the procedure. Always follow the aftercare instructions provided by your dental professional. Key recovery steps include:

• Get some rest! You just went through a challenging procedure and should take it easy.
• Brush and floss gently, especially around the affected area.
• Avoid smoking and tobacco products.
• Avoid hard, difficult-to-chew, and sticky foods to not damage or strain your mouth.
• Use medications as prescribed and follow up with your dental professional if you experience unusual pain or bleeding. Red flag: Contact your dentist immediately if you experience persistent bleeding or signs of infection, such as fever or swelling, lasting more than 48 hours.

Frequently Asked Questions

Can the clinical crown change size?

Yes. Because it is defined by the gumline, any recession or surgical intervention will change how much of the tooth is visible.

What is an artificial crown?

An artificial crown is a restorative cap that replaces most of your entire clinical crown.

Why does gum recession cause sensitivity?

When the gum recedes, the exposed tooth root—which lacks protective enamel and is covered by cementum—becomes vulnerable, making it more susceptible to decay and sensitivity. Clinical note: Exposed roots are highly susceptible to thermal sensitivity because they lack the insulating properties of enamel.

When should I see a specialist?

Always consult with your dental professional to get their expert recommendation on the best procedure for your specific condition.
