Can Chemo Cause Mouth Sores? 

Chemotherapy is a rare example of a treatment that can often feel worse than the illness it seeks to alleviate. That’s because chemo drugs are toxic; they are intended to attack and damage or destroy cancerous cells in the body. But there are almost always side effects, which range from mild to severe. If you or someone you know has gone through or is currently going through chemo, you may know that one of the most debilitating and painful side effects of chemotherapy is the occurrence of mouth sores and mouth ulcers called stomatitis or, more commonly, oral mucositis. This is a side effect of many commonly used chemotherapy drugs, with many factors impacting its onset and severity. Mouth sores can occur throughout the oral cavity including on the hard and soft palate, tongue, gums, cheeks and lips.  

A significant proportion of patients receiving chemotherapy will experience some level of stomatitis or oral mucositis. Besides being painful, mouth sores can cause clinically significant problems including dose-reductions or delays in chemo treatments, prescription opioid use for pain, weight loss from difficulty eating, pathway for infections, and an increased rate of ER visits and hospitalizations. With the onset of mouth sores, it may also be difficult to talk and to sleep which affects quality of life. 

How Does Chemotherapy Work? 

For those not versed in the basics of oncology, chemotherapy is probably the most common cancer treatment available. It’s an example of what doctors call a “systemic” treatment, meaning it affects the entire body. If you get a weekly or biweekly infusion of chemo drugs, that medication circulates throughout your entire body, which is why chemotherapy is often used in tandem with more localized treatments – such as radiation therapy – to seek out and destroy stray cancer cells that may have wandered into other systems in the body. 

Because it’s systemic, however, the side effects of chemo can be felt throughout the body as well. The very things that make chemotherapy drugs effective against cancer are often the things that make chemo so devastating to the body; these toxic chemicals are primed to seek out and attack cells that rapidly divide and grow – a signature trait of cancer cells. However, the medication can’t tell friend from foe and often winds up attacking healthy tissues that exhibit those same traits, especially the hair, nails, bone marrow, and mucous membranes of the mouth and digestive tract. 

Can You Get Mouth Sores from Chemo? 

There are many side effects that are instantly associated with chemotherapy treatment. Hair loss is perhaps the most widely recognized side effect of these treatments. However, a side effect that’s less discussed but much more dangerous is oral mucositis, a condition in which painful sores develop in the mouth and cause several serious problems. 

As mentioned above, chemo is a systemic treatment; that means it affects the entire body, including the mouth. When the chemotherapy drugs circulate through the patient’s system and eventually reach the mucous membranes that line the mouth and tongue, they begin to break down those vulnerable tissues, causing open wounds (sores) to form in the mouth. Not only are these sores painful, but they can also bleed and become inflamed or even infected – a potentially life-threatening development for someone with cancer. 

The Cost of Mouth Sores Caused by Chemo 

It’s no secret that the American medical system often leaves patients with mountains of medical bills following treatment, a fact that’s painfully obvious to those with a serious illness, such as cancer. Stays in the hospital, doses of chemo drugs, and extensive palliative care can add up and the cost of chemo-induced oral mucositis only adds to this problem. 

Treating oral mucositis can easily require patients to spend tens of thousands of dollars on additional care. In fact, a 2008 study published in the journal Dental Clinics of North America found that a single-point increase in the severity of oral mucositis (which is generally measured on a scale of 1-4) led to as much as $25,000 in mucositis-related hospital bills for patients. That’s because this uptick in severity was accompanied by more than twice the risk of serious infection, 2.6 more days in the hospital, 2.6 more days using narcotic painkillers, and 2.7 more days of getting nutrition through an IV. 

Patients who had greater oral mucositis symptoms also had almost four times the risk of death in the first 100 days of treatment. All told, the effects of this condition can have an incredible impact on a patient’s physical and financial health. 

Fighting Mouth Sores Caused by Chemo 

There is often little a patient can do to address the appearance of mouth sores caused by chemo. Once they appear, mouth rinses can be used to help reduce the chances of infection, and patients should follow a strict oral care routine during chemo. Only cryotherapy – the use of cold temperatures to treat the body – has been shown to be effective at reducing the onset and severity of oral mucositis, and the Chemo Mouthpiece® is proven to be very effective as an oral cryotherapy device. Not only is the Chemo Mouthpiece safe and easy to use, but it can cool the entire oral cavity, temporarily shrinking the blood vessels in the area and preventing much of the toxic medication from reaching the soft tissues of the mouth. Try the Chemo Mouthpiece today and see the difference for yourself. 

Try a Clinically Proven Option for Reducing the Risk of Chemo Mouth Sores

Patients going through chemo often complain about the problems that come with mouth sores. Eating, drinking, sleeping and talking can become very difficult, and the pain from mouth sores may even necessitate the use of opioid pain medications. The expenses related to oral mucositis can be significant too. Luckily, the Chemo Mouthpiece can help many patients reduce the occurrence and severity of their symptoms, improving their quality of life and saving them money in the process.
