Last updated on April 27th, 2026

Cosmetic dentistry has several obvious advantages. Many people from around the world are seeking ways to achieve a better smile through various dental treatments. According to a 2020 report from Fortune Business Insights, the global market size for cosmetic dentistry was $23.02 billion in 2018 and is estimated to reach $43.06 billion by 2026.

As the figures suggest, there is a growing interest in cosmetic dentistry nowadays. However, is cosmetic dentistry all it’s cracked up to be? What about risks and complications? In this article, we will explain the potential risks of cosmetic dentistry by touching on various factors. Then, we will give you some tips to minimize the risks of cosmetic dentistry so that you can make the most of your dental treatments without worrying about the end results.

The Potential Risks Of Cosmetic Dentistry

People might have cosmetic issues with their teeth for various reasons, and cosmetic dentistry offers transformative solutions. However, sometimes patients may end up with undesirable results. Here are some of the most common problems that patients may experience during or after a cosmetic dentistry treatment.

Allergic Reactions

Cosmetic dentistry materials may cause allergic reactions. According to a 2015 study published in The Journal of Diagnostic and Clinical Research, latex and polymethyl methacrylate can lead to delayed hypersensitivity reactions. As well as sodium metabisulfite and nickel, which can cause immediate allergic reactions. Therefore, patients and dentists should consider the patient’s documented allergies before starting any cosmetic dentistry treatment.

Complications From Anesthesia

Anesthesia is an effective way to avoid pain during treatment, but it can cause certain problems for some patients. Usually, general anesthesia carries a higher risk of complications. Fortunately, cosmetic dentistry rarely uses general anesthesia. Although reactions to anesthesia can vary from one patient to another, the most common are nausea or vomiting, headache, shivering, sweating, dry mouth, and sore throat.

Damage To Teeth And Gums

Some cosmetic dentistry procedures might cause problems with hard and soft tissues in and around patients’ mouths. Here are the different types of risks involved in cosmetic dentistry.

Tooth Sensitivity

Tooth sensitivity is among the most common risks of cosmetic dentistry that patients experience soon after getting veneers. The sensitivity is greater if the nerve of the tooth was affected by the grinding down of the tooth surface. Also, teeth may be sensitive to hot or cold beverages after getting veneers. The risk of sensitivity is not limited to veneer treatment. For example,teeth whitening can cause tenderness and sensitivity due to some materials used in the procedure such as hydrogen peroxide and carbamide.

Tooth Damage (Damage to Tooth Enamel)

Damage to the tooth can pose a risk during an enamel-shaping treatment if the dental professional is not sufficiently experienced or careless. However, some additional procedures can rectify any persistent problems you may have with your teeth if damage has occurred.

 Gum Irritation 

Gum irritation is a common side effect that patients may experience after teeth whitening. The chemicals used in the whitening procedure may cause inflammation or irritation, leading to further swelling and discomfort.

Nerve Damage

Nerve damage is a potential risk in some of the anesthesia and dental implant treatments. It is very rare but can be potentially dangerous. Some of the damages can be corrected, while others may become permanent. Therefore, choosing an experienced, competent dentist is critical for patients.

Infection

Veneers or dental implants might cause infections in the tooth structure or gum tissue. Patients usually notice an infection through pain or swelling. Most infections clear up within a couple of days after treatment. If an infection persists or worsens, you should see your dentist. Dentists can clean the area and/or prescribe antibiotics. In some cases, the dental implant itself can cause an infection. In such cases, the implant needs to be removed.

Unsatisfactory Results

Some patients might not be completely satisfied by the results because the new appearance of their smile doesn’t look as beautiful as they had imagined. Even if there were no complications or side effects for the patient, he/she might still feel disappointed with the results.

Such problems usually stem from the lack of communication. Many people want a smile like a celebrity they see on TV. However, a Hollywood smile may not be appropriate for his/her face. A customized smile design is much more important than creating a fabricated look on a patient. Therefore, dental professionals or clinics should listen to their patients carefully and explain the steps they will follow by illustrating a digital preview of the projected outcome. 

Bite Issues 

Common cosmetic dentistry procedures, such as veneers, crowns, or implants, might lead to bite issues. For example, bulky veneers or improperly placed crowns can disrupt the balance of upper and lower tooth alignment, leading to an overbite, underbite, or other bite problems.

What Are The Causes Of The Potential Problems? 

Here are a few of the most common causes of problems following cosmetic dentistry treatments. 

Unqualified Practitioners

Unqualified or inexperienced dental professionals may have difficulty performing certain cosmetic dentistry procedures, which can lead to some of the problems listed above. Patients should seek qualified, experienced dentists for any and all treatments they need.

Poor Oral Care

Some patients may experience delayed complications or other problems after receiving cosmetic dental treatment, even if the treatment was very successful. Most of the time, it was found that patients didn’t follow the oral care routines (toothbrushing regularly, flossing, avoiding certain food or drinks ..etc.) prescribed by dentists. Therefore, it is very important for patients to maintain proper oral care.

Poor Communication

Patients and dental professionals need strong communication before treatment can occur. The patient’s needs and expectations should be clear and practical for both parties. Also, if the patient has any health issues, he/she should inform the dentist about them so that the dentist can tailor a treatment plan for the patient. 

How To Reduce The Risks Of Cosmetic Dentistry?

We should acknowledge that eliminating the risks of cosmetic dentistry completely is not possible. However, there are still ways to reduce the risk of postoperative problems. 

Choosing a reputable, experienced cosmetic dentist is one of the first steps you can take to avoid unwanted results. When searching for a good cosmetic dentist, you should also consider the dentist’s communication skills. Remember that good communication is not limited to speaking your native language. A good dentist should listen to you carefully and discuss your case in a collaborative manner. At this point, informing your dentist of any allergies or medical conditions is critical. Only then, you can expect him/her to blend their theoretical knowledge to deal with your case properly.

Moreover, closely monitoring your oral health after the procedure is another key to a positive cosmetic dental experience. A good follow-up appointment can drastically reduce the risk of complications in cosmetic dentistry. On the other hand, making the most of this monitoring requires your cooperation, as well. Note that almost any dentist will give you proper aftercare instructions following treatment. But it is your responsibility to follow those instructions to avoid the risks of cosmetic dentistry.
