مقدمه

کامپوزیت دندان یکی از رایج‌ترین روش‌های ترمیمی و زیبایی در دندان‌پزشکی مدرن است. این روش به دلیل زیبایی، هزینه مناسب‌تر نسبت به ونیرهای سرامیکی و قابلیت اجرای سریع، محبوبیت زیادی پیدا کرده است. But the question of many clients is: Is dental composite permanent? Or does it need repair and replacement?

In this article, we are trying to comprehensively address the durability of dental composite, examine the factors affecting its durability and provide tips to increase the life of composites.

What is dental composite?

Dental composite is a resin material that is used to repair caries, close the gap between teeth, correct the shape and color of teeth, or as a composite veneer for a beautiful smile. This material is a combination of resin particles and mineral fillers, and after being placed on the tooth, it hardens with blue light.

Is dental composite permanent?

The short answer is: No, dental composite is not permanent, but it can last for years.

Composites, like any other restorative material, have a certain lifespan and may need to be repaired or replaced under the influence of various factors. On average, the durability of dental composite is between 5 and 8 years, but with proper care, this period can be extended even up to 10 years or more.

factors affecting the durability of tooth composite

The durability and longevity of composite depends on various factors. The most important of these factors are:

1. Dentist skill

Correct execution of composite, tooth surface preparation, basic layering and final finishing all require precision and expertise. An experienced dentist can significantly increase the durability of the composite.

2. Quality of composite materials

The type and brand of composite used also plays an important role in its durability. Nano-hybrid or micro-hybrid composites have higher quality.

3. Placement of composite

Anterior composites (front teeth) usually last longer because they are less stressed than posterior (back) teeth.

4. Oral hygiene

Observation of oral hygiene (brush, dental floss, mouthwash) and regular visits to the dentist will reduce the possibility of decay around the composite and increase its lifespan.

5. Oral habits of the patient

Habit to grind your teeth, chew ice or nails, open things with your teeth and eat very hard or sticky foods can cause the composite to break or chip more quickly.

Signs of the need to replace or repair dental composite

After a few years of use, signs may appear that indicate the need to replace or repair the composite. The most important of these symptoms are:

• Composite color change (yellowing or staining)

• cracking or chipping

• Separation of the composite from the tooth surface

• feeling unfair or rough

• tooth decay around the composite

• Pain or tenderness at the repaired site

If you see any of these things, it is better to go to the dentist as soon as possible to prevent further damage to the teeth.

Difference between durability of composite and ceramic laminate

Many people hesitate between composite and ceramic laminate. One of the main differences between the two is in their durability and resistance:

If you are looking for an affordable option with the possibility of restoration, composite is the right choice; But if durability and high resistance is a priority for you, laminate can be better.

How to increase the life of tooth composite?

By following a few simple tips, you can significantly increase the durability of tooth composite:

Brush your teeth at least twice a day with a soft toothbrush

daily use of dental floss to prevent interdental caries

✅ avoid eating hard foods (ice, hot pot, raw nuts)

✅ Not consuming large amounts of colored drinks (coffee, tea, soft drinks)

No smoking

✅ Using a night guard (night guard) if you have teeth grinding

regular visits to the dentist for polishing and examination of composites

Is dental composite polishing necessary?

Yes. Over time, the composite surface may become roughened and scaled or discolored. Periodic polishing (every 6 to 12 months) restores the shine, removes stains and increases the life of the composite.

Is it possible to whiten composite teeth?

No. Unlike natural teeth, composites are not affected by bleaching or tooth whiteners. Therefore, before doing composite veneers, if you intend to whiten your teeth, bleaching should be done first, and then the color of the composite should be selected according to the bleached tooth.

How much does composite cost and is it worth it?

The cost of dental composite varies depending on the number of teeth, the type of material, the skill of the dentist and the geographical area. Although composite is cheaper than laminate, it is still an investment for the beauty of the smile.

With proper care, composites can give you a beautiful smile for years and are great value for money.

Is composite suitable for everyone?

Composite is a good choice for many people, but it may not be a good choice in the following situations:

• Teeth that are severely worn

• People with poor oral hygiene

• Patients with severe grinding

• Those who are looking for extensive changes in the shape of the teeth (in this case, laminate is better)
