How Long Does Dental Bonding Last?

How Long Does Dental Bonding Last?

Dental bonding is a long-lasting restorative treatment option for restoring chipped and crooked teeth to their natural contour.
Nowadays, we have modern materials that are famous for their longevity and effectively match the shade and color of natural teeth.
This makes dental restoration indistinguishable from the remaining natural tooth. But exactly how long does dental bonding last? Let’s discuss these things in detail: 

What Is Dental Bonding?

In order to understand, ‘How long does dental bonding last?’ It is essential to know the basics of it. Dental bonding is a minimally invasive, restorative procedure that restores the shape, contour, and functions of crooked, chipped, minimally damaged, and stained teeth. No enamel surface is shaved off in the procedure of dental bonding. 

However, in the case of veneers and crowns, a thin layer of enamel is to be removed, and then that surface is prepared where this prosthesis can be bonded. Dental bonding is one of the most conservative dental procedures.

Is Composite the Best Dental Bonding Material?

Composite is an ideal dental bonding material. It is because:

  • The color of the composite is comparable to the natural tooth surface. 
  • Different shades are available of composite.
  • It has an aesthetic appeal.
  • The strength of composite resists deformation

How Long Does Composite Bonding Last?

Composite bonding generally lasts between four to eight years. However, it highly relies on the tooth’s location, restoration depth, quality of restorative material, oral hygiene of the patient, and eating habits. 

Eating habits matter a lot. For instance, if a patient breaks walnuts and opens bottle caps with composite-restored teeth, the restoration would hardly survive a few years. On the other hand, if a patient maintains proper oral hygiene and regularly visits the dentist for follow-ups, then the life of composite bonding may exceed eight to ten years.

How Polymerization Shrinkage Can Reduce the Life of Dental Bonding?

However, despite being one of the most ideal bonding materials, composites also have weaknesses. Polymerized shrinkage is a phenomenon that refers to the shrinking of the restoration after the filling has been cured. 

This may lead to more issues like microleakage. Polymerization shrinkage may result from poorly done filling and an improper choice of bonding material. However, according to research, bulk-fill resin composites show lower polymerization shrinkage and present with more microhardness than conventional ones. 

After exposure to light for curing, bulk-fill resin composite shows a depth of cure higher than 4.5mm, which is way more than that of conventional composite bonding materials. 

How Long Does Dental Bonding Last On Front Teeth?

Front teeth mainly refer to incisors and canines. When you smile, these teeth and the premolars are usually visible. How long does dental bonding lasts on these teeth is an important question, as they directly impact your overall appearance. The anterior teeth are the first to encounter any food or beverage we consume. Usually, the edges of incisors or canines are chipped, and those edges need frequent composite replacements. 

Being the first teeth to encounter biting or breaking the food, these are more prone to breakage. However, with proper care, precautions, and careful cleaning, the life of dental bonding on anterior teeth may last up to 10 or more years. Annually, about 1-5% of composite restorations fail in anterior teeth, with the rest being successful. 

Factors Affecting Dental Bonding

Some factors affect the success of every bonding treatment. To understand “how long does dental bonding last?” you must understand these factors thoroughly. These factors include:

  • Moisture control during dental bonding
  •  Proper following of steps during this dental procedure 
  • The type of composite or bonding material used. More bulk of resin in composite means greater depth of cure and ensures the longevity of dental bonding. 
  • Use the right etchant(37% phosphoric acid) and a dental bonding agent. These liquids are applied on the tooth’s surface before applying the bonding material. The etchant makes the tooth’s surface porous, while the bonding agent forms a bond between the bonding material and the tooth’s surface. 
  • Expertise of the dentist. A cosmetic and restorative dentist would be a better choice. 
  • Patients’ habits also affect the success of dental bonding. Habits like grinding teeth or using teeth to cut materials like tape and cloth will hurt the life of dental bonding. 

Increasing the Life Of Dental Bonding

To extend the life of dental bonding, various habits can be incorporated into daily life. For instance,

  • Maintain oral hygiene by using floss, toothbrush, and occasional rinse with salt and water. 
  • Secondly, it is mandatory to prevent biting on complex objects, whether nuts or ice cubes. 
  • Smoking is not just hazardous to overall health, but it also reduces the lifespan of dental bonding. Therefore, quitting smoking is essential to enhance the lifespan of the treated tooth. 
  • Food and beverages that tend to stain the teeth, such as beetroot, apple cider vinegar, and soft drinks, should be reduced in the diet. These stains are difficult to remove and may even require replacement. 
  • If you face the issue of bruxism or teeth grinding, your dentist may prescribe you the regular usage of mouthguards at night. You can place these night mouthguards before sleeping. This will prevent subconscious teeth from grinding. 
  • Not missing your follow-up check with the dentist is the best favor you will do yourself. 

When to See a Dentist?

If you have had dental bonding on your teeth and suddenly your restoration has chipped off or broken in an accident or a rigid and deep bite on a burger or food, you must visit the dentist. The sooner it is, the better. The dentist may restore the tooth’s form, contour, and strength in the same appointment. This prevents your aesthetics and function from being compromised. Seeing the dentist on priority also prevents further breakage of the tooth.
