Chlorhexidine Mouthwash: Great for Dental Patients

One of the most reliable antimicrobial rinses in modern dentistry is chlorhexidine mouthwash. At our dental office, we frequently also prescribe it to assist patients in dealing with gum issues, infections, and to help patients heal after dental treatment. The reason is that chlorhexidine mouthwash is a gold-standard intervention to manage various conditions of the mouth due to its high levels of antibacterial protection and long-term effects. It is a more detailed guide as to what it is, how it works, how to use it safely, who should avoid it, and what the alternatives are.

What is Chlorhexidine Mouthwash?

Chlorhexidine mouthwash is a prescription-grade mouthwash which was developed based on the chlorhexidine gluconate concentration, typically 0.12 or 0.2%. It is to kill bacteria responsible for causing gum disease, infection, and inflammation. The rinse is bonded to the teeth and the gums and the other soft tissues, and thus works long after spit has removed it.

Chlorhexidine mouthwash is mainly applied in dentistry since it provides a wide range of antimicrobial coverage. It decreases detrimental bacteria that cause gum bleeding, poor breath, plaque accumulation and oral infections. Although other over-the-counter products boast similar benefits, none is as effective as chlorhexidine mouthwash, hence the popularity of the latter in dental clinics all over the world.

Although there are some debates online about whether or not chlorhexidine is still in use, or if it is being phased out, the fact remains that it remains a common clinical device. It is just that dentists prescribe it only more selectively nowadays to avoid misuse and taking needless side effects.

Mechanism of Action of Chlorhexidine Mouthwash.

Mechanism of Action of Chlorhexidine Mouthwash.

Chlorhexidine is effective because it attaches to surfaces within the mouth and releases antibacterial activity slowly through the course of the day. This is what is referred to as substantivity and is what makes the chlorhexidine mouthwash more effective as compared to the regular mouthwash.

It has several essential functions:

  • Destroys gum disease-causing bacteria.
  • Eliminates the development of plaque and tartar.
  • Prevent postoperative infections in dentistry.
  • Reduces gum inflammation
  • Messy breath due to bacterial formation.
  • Helps shorten the healing time of inaccessible places.

Such an effect of chlorhexidine mouthwash is that since the product has long-term protection, the patient can often see significant improvement after just a few days of regular use.

In the case of Our Dental Clinic, Prescribing Chlorhexidine

Chlorhexidine mouthwash is provided when it is needed and never in the long term. It is particularly useful when there are the following situations:

1. Gingivitis (Early Gum Disease)

Chlorhexidine lowers the activity of bacteria and inflammation, which contributes to faster healing of gums. It is commonly prescribed when bleeding gums do not stop even after brushing them on a regular basis.

2. Periodontitis (Advanced Gum Disease)

After deep cleaning (scaling and root planing), chlorhexidine mouthwash must be used to ensure that there is a cleaner environment, and the gums may reattach and heal.

3. After Surgery or Dental Surgery

It is usually prescribed following the following procedures:

  • Tooth extraction
  • Dental implant placement
  • Crown lengthening
  • Periodontal surgery
  • Scaling and polishing

It has an antimicrobial effect which serves to protect the areas requiring healing and reduces the possibility of getting infected.

4. Soft Tissue Infection or Oral Ulcers

Chlorhexidine can decrease irritation, pain and bacterial numbers to enable soft tissue to recover more effectively.

5. Limited Brushing Ability

During the process of recovering after surgery, the elderly or individuals with some form of disability may temporarily adopt the use of chlorhexidine mouthwash when it is hard to brush their teeth.

6. Halitosis Due to Bacteria

Bad breath associated with gum disease or accumulation of bacteria usually resolves within a short period of time when chlorhexidine is used.
