Why Cancer Patients Need Special Dental Care Before Chemotherapy

After the immediate shock of a cancer diagnosis, it’s natural to focus on meeting your oncologist and learning about your specific treatment plan. You might have to deal with a lot of new and difficult challenges, from managing your emotions to preparing for what’s to come. Thinking about visiting a dentist at a time like this would understandably be the last thing on your mind.

However, there is a significant medical reason your oncologist would have you go to a dentist for a required checkup before you undergo chemotherapy.

This circumstance would not fall under the category of a routine or cosmetic dental visit. A required dental checkup before starting chemotherapy is a safety measure based on existing medical research that is meant to detect and resolve undiagnosed dental health issues before the body’s defense against infection is compromised. Solving your dental issues at this time would actually promote the effectiveness of your cancer treatment by preventing pain, reducing the chance of an interruption in treatment, and keeping the whole process more accommodating and easier.

Sadly, very little is said about this in Pakistan, even though it is a standard part of cancer care around the globe. This guide is designed to help you understand the importance of dental care for cancer patients, what a pre-treatment dental evaluation entails, and the role of Dental Aesthetics Lahore, in partnership with Oncologists, to help patients prepare for their strongest support to fight cancer: their chemotherapy.

How Chemotherapy Impacts Oral Health

Chemotherapy is designed to target and kill rapidly multiplying cancer cells; however, cells in your mouth are also healthy and multiply rapidly and are also impacted. Because your immune system is weakened, even the most mundane dental health issues can escalate in severity.

Because of the potential issues that can arise from the interaction of chemotherapy and the immune system and the impact and rapid deterioration of oral health, most dentists prefer to manage oral health issues prior to the start of chemotherapy treatment.

Common Oral Side Effects from Chemotherapy

1. Oral Mucositis

This is one of the main mouth problems caused by chemotherapy. Oral mucositis is painful inflammation and sores on the lining of the mouth.

1. Xerostomia (Dry Mouth)

Dry mouth from chemotherapy is when xerostomia (the lack of mouth moisture) occurs.

Saliva protects teeth, maintains a healthy population of oral bacteria, and aids digestion by moistening food and forming a bolus. A lack of saliva leads to:

• Cavities

• Gum disease

• Mouth Infections

• Dysgeusia

While chemotherapy is a temporary treatment, many people can find an unfamiliar metallic, bitter and even blank taste to common foods. This can make eating difficult.

1. Dysgeusia

Another common side effect is the sudden bad or metallic taste to food, which can make eating very difficult during chemotherapy.

1. Increased Infection Risk

Chemotherapy also significantly reduces white blood cell count (and more importantly, the absolute neutrophil count). This also lowers the body's ability to fight oral bacteria.

Gum disease, tooth cavities, and even dental abscesses can quickly get out of control when the body's defense mechanisms are so low.

1. Oral Thrush and Cold Sores

Oral thrush and the condition known as cold sores can both develop during chemotherapy. Oral thrush is caused by the fungus Candida, and chemotherapy can reactivate the herpes simplex virus, which causes cold sores.

The earlier these conditions are treated, the better. They worsen if they are ignored during the course of treatment. If chemotherapy includes radiation to the neck and head, your dentist will discuss the possibility of dry mouth and jaw bone necrosis caused by radiation. Patients on bisphosphonate medications that strengthen bones may also be evaluated for medication-related osteonecrosis of the jaw (MRONJ).

What Pakistani Research Shows

Research studies originating from Aga Khan University in Karachi focused on the oral care of chemotherapy patients and found that approximately 26% of participants improved their oral care. This signifies that instruction in oral care along with the use of a toothbrush significantly improved the oral care of patients undergoing cancer treatment.

Another study from Karachi focused on breast cancer patients and found that the frequency of teeth brushing was negatively correlated with the incidence of oral mucositis. The conclusion of these studies is that oral care is especially important during the treatment of cancer.

Why a Dental Checkup Before Chemotherapy Is Necessary

Some patients question why a dentist should be involved prior to the onset of cancer treatment. The answer is that a dental checkup prior to the onset of chemotherapy gives your dentist the opportunity to discover existing infections while your immune system is still fully functioning.

Why Timing Matters

Hidden problems like:

• Deep Cavity

• Gum Disease

• Dental Abscess

• Broken Teeth

• Poorly Fitting Dentures

These may appear minor prior to the start of chemotherapy, but they will be much more difficult to treat once chemotherapy has started.

When your immunity is reduced due to chemotherapy, bacteria can travel from infected Teeth to your blood and cause complications which your oncology team would like to avoid.

Then we have the concept of 'nadir.' Nadir refers to the time post-chemotherapy when your Blood generally reaches its lowest level (7-14 days).

During this period, you will see:

• Higher Platelet Transfer Risk

• Higher Infection Risk

• The Healing Slower

Because of this, dentists prefer all oral surgeries to be at least 7-10 days prior to the start of the chemotherapy, so they can heal.

The healing timelines are coordinated between your dentist and oncologist.

Your oncology team will also look at your white blood cell levels and your platelet levels.

Safe, coordinated care is the priority.

What Happens During a Pre-Chemotherapy Dental Checkup?

More than just a typical dental cleaning, a dental checkup prior to Chemotherapy is more thorough and focuses on clearing up potential infection sources.

Your Visit at Dental Aesthetics Lahore

During your appointment, the dentist carefully checks for:

• Cavities

• Gum Disease

• Broken or Cracked Teeth

• Dental Abscesses

• Poorly Fitting Dentures

• Irritating Orthodontic Appliances

• Oral Infections

• Soft Tissue Lesions

Scaling eliminates plaque and tartar. Professional scaling is particularly important for cancer patient's due to the level of bacteria in the mouth. In the event that decay and gum disease are diagnosed, necessary dental treatment that is deemed safe for cancer patients typically is performed prior to the start of chemotherapy.

It is not uncommon for patients to have a tooth that is deemed unlikely to last the duration of several months of chemotherapy. In these cases, the dentist may recommend extraction be performed prior to chemotherapy to avoid an emergency situation.

The dentist will detail the expected oral care prior to chemotherapy as well as the brushing, mouth rinsing, hydration and foods that are less likely to irritate the oral tissues. Dental Aesthetics Lahore will prepare your treatment plan and share with your Oncologist when necessary.

Oral Care Before Chemotherapy and Oral Hygiene During Cancer Treatment

The importance of good oral care does not end after your dental appointment before chemotherapy. Excellent oral hygiene throughout your cancer treatment will decrease level of discomfort and help lower the risk of oral infections.

Daily Oral Health Recommendations

Brushing may worsen sores in the mouth, but neglecting hygiene worsens bacteria in the mouth and increases the risk of infection more. The dentist and oncologist can provide supportive care and symptom relief.

Why Special Dental Care Before Chemotherapy Matters in Pakistan

Pakistan is one of the highest-risk nations for oral cavity cancer, a fact highlighted by a study from the Shaukat Khanum Memorial Cancer Hospital & Research Centre. Even though this article is not about oral cancer and is about chemotherapy, it shows how important it is to focus on oral health. There is also another important consideration.

A study in 2023 on 468 physicians from Saudi Arabia shows that just more than half exhibit poor oral health awareness, particularly on the need for dental referrals prior to chemotherapy and radiotherapy. This is poor awareness, and even if it is not Pakistan, it shows that pre-treatment dental referrals are not always mandatory.

Because of this reason, patients and their families are entitled to ask if a dental clearance is needed prior to starting any oncology treatment. It is important to understand this so that the patient can receive better care.

When to Get a Dental Checkup Before Chemotherapy?

It is best to get the dental check done as soon as the patient knows for certain that the scheduling for chemo has been confirmed.

The suggested timing is 1-2 weeks prior to the first chemotherapy session, as it allows sufficient time for healing, should we have to carry out fillings, deep cleanings, or even extractions.

This assessment is usually scheduled within the cancer treatment plan and will not delay the chemotherapy. Planning this evaluation earlier gives more options for both your oncologist and dentist.
