What is Ferritin /Iron testing?
Ferritin is a protein that stores iron in your body. Iron helps carry oxygen around your body and is essential for healthy tissues, wound healing and a strong immune system. When ferritin levels are low, your body may struggle to repair itself efficiently, which can also affect your oral health.[1][2]
At Dental Rooms Wimbledon, we believe your mouth is part of your overall health. Understanding your ferritin level by doing Iron testing can help us plan dental treatment more effectively, especially if you’re having oral surgery or dental implants.
How Can Low Iron Affect Your Mouth?
Many people are surprised to learn that iron deficiency often shows its first signs inside the mouth.
Symptoms may include:
- Recurrent mouth ulcers
- Burning Mouth Syndrome
- A sore, smooth or swollen tongue (atrophic glossitis)
- Pale gums
- Dry mouth
- Increased oral infections
- Delayed healing after dental procedures
- Increased tiredness affecting oral hygiene habits[3][4]
Ferritin and Dental Implants
Dental implants rely on your body creating healthy new bone around the implant – a process called osseointegration.
Iron plays an important role in:
- oxygen delivery to healing tissues
- collagen production
- immune function
- wound healing
- tissue repair[5]
If iron stores are very low, healing after implant placement or bone grafting may be slower. While ferritin alone doesn’t determine implant success, correcting an iron deficiency beforehand may support a smoother recovery.[6][7]
Ferritin and Oral Surgery
Good iron levels may also support healing after:
- Wisdom tooth removal
- Tooth extractions
- Bone grafting
- Gum surgery
- Dental implant surgery
- Periodontal treatment
Healthy oxygen delivery helps tissues repair efficiently and reduces prolonged healing times.[5]
Gum Health
Research suggests iron deficiency may contribute to:
- inflamed gums
- slower gum healing
- increased susceptibility to infection
- discomfort during periodontal disease
Maintaining healthy iron stores supports the immune system, which plays an important role in protecting your gums from harmful bacteria.[3][8]
Who Should Consider Ferritin Testing?
Iron deficiency is particularly common in:
- Women with heavy menstrual periods
- Pregnancy and post-partum
- Vegetarians and vegans
- Endurance athletes
- People with digestive disorders
- Patients with unexplained fatigue
- Patients preparing for dental implants or oral surgery[2]
Benefits of Ferritin Testing Before Dental Treatment
Knowing your ferritin level may help:
- optimise healing before surgery
- identify nutritional deficiencies
- personalise treatment planning
- support healthy gums
- improve recovery after extractions
- support implant healing
- provide reassurance before complex treatment
FAQs
Can low iron cause mouth ulcers?
Yes. Iron deficiency is one of the recognised nutritional causes of recurrent mouth ulcers and soreness.[3]
Can low ferritin affect dental implants?
Low ferritin doesn’t automatically mean implants will fail, but healthy iron stores support normal healing and tissue repair.[6]
Should I take iron supplements before dental treatment?
Only if recommended by your GP or healthcare professional after blood testing.
Can low iron make my gums pale?
Yes. Pale gums can sometimes be a sign of iron deficiency anaemia.[2]
Is ferritin testing painful?
No. It is a simple blood test that can provide valuable information about your overall health.
