Breast cancer and oral health
Discover the importance of oral care during and after an oncological problem
October is the pink month, dedicated to raising awareness about breast cancer, the importance of early diagnosis and support for all women facing this disease. It is a month of reflection and prevention, but also of strengthening what often goes unnoticed. An example of this is oral health during cancer treatments.
The impact of cancer extends far beyond the affected site. Chemotherapy, radiotherapy and hormone therapies often cause significant changes in the mouth and teeth, making specialized monitoring essential. In our dental clinic, in Vila Franca de Xira, we are fully aware that caring for the smile is also an estimate of overall health, especially in moments of greater fragility.

Effects of cancer treatments on oral health
Breast cancer is the most common type of cancer (excluding skin cancer) among women and is the leading cause of death from cancer.
In Portugal, about 7,000 new cases of breast cancer are detected annually, with more than 2000 women dying from this disease, says the Portuguese League Against Cancer. If detected and treated early has a cure rate above 90%.
Still, it is not a woman-only pathology. According to the same organism, about 1% of all breast cancers are in men.
In addition, this disease ends up bringing other complications that can impact other organs, such as the oral cavity.
According to a study in the journal Research, Society and Development (2021)*, “chemotherapeutic oncological treatment is invariably responsible for triggering oral changes resulting from decreased immune response of the patient. Chemotherapy is one of the most used and effective forms of oncological treatment, however it triggers numerous side effects in all organic systems, including oral cavity. Among them is mucositis, one of the causes of most discomfort for the patient, also responsible for an instability in their quality of life.”
Several studies show that patients undergoing cancer treatment often have effects such as:
- Dry mouth (xerostomy);
- Oral mucositis (inflammation and wounds in the mucosa);
- Changes in taste (dysgeusia);
- Increased risk of cavities;
- Fungal and bacterial infections in the mouth.
These complications can compromise quality of life and, in some cases, require adjustments to cancer treatment.
That is why the Order of Dentists (OMD) reinforces the need for regular oral evaluation consultations in cancer patients, emphasizing that prevention and close follow-up are fundamental to avoid more serious complications and improve daily comfort.
Oral hygiene consultations: a pillar of prevention in the relationship between breast cancer and oral health
As we mentioned earlier, it is easy to notice that during chemotherapy or radiotherapy, the mouth becomes more sensitive and vulnerable. During this period, oral hygiene consultations have gained even more relevance, as they allow:
- To control plaque;
- Prevent cavities and gingivitis;
- Adapt the oral cleansing routine to the new needs of the patient.
Small gestures like using soft brushes, low-abrasiveness toothpastes and alcohol-free cheeks make a big difference. But only regular professional monitoring ensures that the mouth remains healthy, reducing pain, infections and discomfort.
After the fight against cancer recover or smile
Overcoming cancer, in this case breast cancer is undoubtedly a victory! However, many patients have oral sequelae, either due to tooth loss or wear caused by treatments.
Dental implantology emerges as a safe and effective solution to restore masticatory function, aesthetics and self-confidence. The placement of implants, properly planned after the active phase of treatment, such as the one we performed in A Clínica, allows us to restore quality of life and restore the freedom to smile without fear, by placing dental implants after cancer.
The invitation of "Pink October" to care
This month reminds us that health must be taken care of globally. For those undergoing cancer treatment, oral health is not just aesthetic; it is an integral part of therapeutic success, comfort and self-esteem.
If you are undergoing or have completed oncological treatment, do not delay your oral health. Schedule an oral hygiene consultation or an implantology assessment at our dental clinic in Vila Franca de Xira.
Precisely one of the initial questions that we are most often asked is: Who does chemotherapy can go to the dentist?
As you’ve noticed throughout this article, not only can you, but you can find extra strength to win one of the biggest battles!
