Exercises should have a clear purpose; they should not be presented as a guaranteed cure for every breathing, bite or sleep concern.”
03 / YOUR CARE IN MARBELLA
Biological dentist · airway & myofunctional care
Biological & restorative dentistry
Your dental history, current medicines, sensitivity and preferences all belong in the assessment. Dr. Sara can discuss prevention, tooth preservation and restorative options without assuming that one material or one treatment is right for everybody.
Start with a dental assessmentSleep apnea & dental oral appliances
Snoring, pauses in breathing and persistent daytime tiredness warrant medical assessment. A custom oral appliance may be suitable for some people with diagnosed obstructive sleep apnea. Dental assessment, a prescription where appropriate and follow-up help establish whether it is a suitable option.
Understand sleep apneaMyofunctional appliances & oral habits
An assessment can explore oral habits, tongue function and how the teeth and jaws work together. Myofunctional exercises, appliances and orthodontic treatment have different purposes. The choice should follow a diagnosis and discussion of the evidence, expected benefits and limits.
Explore orthodontic care“A mandibular advancement device is an oral appliance that positions the lower jaw forward during sleep. It may be used for selected snoring or obstructive sleep apnea cases. The decision involves assessing the teeth, gums, jaw comfort and medical diagnosis before fitting and follow-up.”

How do I choose the best biological dentist in Marbella?
Dr. Sara combines general dental care with an interest in airway health, sleep apnea oral appliances and myofunctional care. Her education includes the University of Granada and further training in Barcelona. A good choice of biological dentist should bring clear explanations about treatment, materials and evidence, including when a medical sleep assessment is needed.
Is this a replacement for a medical sleep consultation?
No. A dental assessment can contribute to care, but suspected sleep apnea needs appropriate medical evaluation. Bring existing sleep-study results if you have them.
Biological dentistry7 questions · A considered approach to the whole person.
What does biological dentistry mean on this page?
It means discussing oral health in the context of your medical history, habits and concerns. Treatment decisions should still follow dental findings and evidence, with the benefits and limits explained.
Can I discuss sensitivity to dental materials?
Yes. Bring details of any diagnosed allergy or previous reaction. The dentist can discuss the relevance to proposed materials and whether information from another clinician is needed.
Does biological dentistry mean removing healthy dental work?
No automatic removal policy is implied. Ask for the clinical reason, alternatives and risks before replacing an existing restoration or undertaking any irreversible treatment.
Can dental care cure unrelated illnesses?
This page makes no such promise. Dental problems should be assessed on their findings, and non-dental symptoms should also be discussed with the appropriate medical professional.
How should I choose a biological dentist in Marbella?
“Ask how the dentist reaches a diagnosis and explains the benefits and limitations of treatment. Your concerns about materials or general health deserve to be heard. A useful consultation turns those concerns into specific questions that can be assessed, rather than assuming a diagnosis from the label alone.”
Is holistic dentistry a separate answer to every health concern?
“People use the word holistic in different ways. I take it to mean considering the person as well as the teeth, while staying within what dental assessment can establish. Some concerns need medical input, and I would explain when another professional should be involved.”
Does a biological approach mean avoiding necessary treatment?
“Preserving tooth structure is important, but delaying treatment can also allow a problem to progress. I explain the findings, reasonable alternatives and what monitoring would involve. The decision should balance the benefits of intervention with its effects on the tooth and your own priorities.”
Sleep apnea & snoring8 questions · Dental care within a wider diagnostic pathway.
Can snoring be a sign of sleep apnea?
It can be, but snoring alone does not establish the diagnosis. Pauses in breathing or persistent daytime tiredness are reasons to seek medical assessment.
Can Dr. Sara discuss an oral appliance for sleep apnea?
Her clinic biography records training in oral appliances for snoring and obstructive sleep apnea. An appointment can explore dental suitability alongside your medical diagnosis and treatment plan.
Is a sleep apnea appliance the same as a grinding splint?
No. Appliances can have different purposes and designs. Tell the dentist what diagnosis you have and bring any existing appliance so its role can be reviewed.
Can I stop using CPAP if I book a dental consultation?
Do not change prescribed treatment on the basis of this page. Discuss any change with your treating sleep clinician, including how a proposed alternative would be assessed.
Can a sleep apnea mouth guard treat every patient?
“An oral appliance can be appropriate for selected patients with obstructive sleep apnea, following medical assessment. The choice should be coordinated with the sleep clinician. A dental device is not a universal replacement for other prescribed treatment, and its effectiveness needs follow-up.”
Is a snoring mouthguard enough if I stop breathing in sleep?
“Reported pauses in breathing need medical assessment. Snoring alone does not establish whether sleep apnea is present or how severe it is. I can discuss dental findings and oral-appliance options, but a sleep evaluation should guide the diagnosis and overall treatment plan.”
What should I bring to an airway related dental consultation?
“Bring any sleep-study report, current treatment details and a list of medicines. Describe snoring, waking symptoms and anything a partner has noticed. These details help us understand the reason for the referral and work with the clinician responsible for your sleep diagnosis.”
Can I stop using CPAP when I receive a dental appliance?
“Do not change prescribed sleep treatment on your own. An oral appliance needs to be assessed within your overall care plan, including whether it controls the condition adequately. Changes to CPAP or other treatment should be agreed with the clinician managing your sleep apnea.”
Myofunctional care & appliances8 questions · Understand the purpose of each recommendation.
What can a myofunctional assessment explore?
It may examine oral habits and how the tongue, lips and jaws function. The clinician should explain the findings and what, if any, exercises, appliance or referral is appropriate.
Are exercises and appliances interchangeable?
No. They have different intended purposes. Ask what the recommendation is meant to address, how progress will be reviewed and what evidence supports it in your situation.
Can an appliance guarantee better sleep?
No. The effect of treatment needs to be assessed rather than assumed. Symptoms alone may not establish that sleep apnea is adequately controlled.
Can I ask about my child’s mouth breathing?
Yes, while also discussing persistent breathing or sleep concerns with the child’s medical clinician. The dental team can explain when orthodontic or other assessment is appropriate.
Is an anti snoring mouthpiece the same as a fitted appliance?
“Devices differ in fit, adjustment and clinical supervision. A product bought without assessment cannot tell you why you snore or whether sleep apnea is present. I would first establish the clinical context and discuss whether an individually fitted appliance is appropriate.”
Is a night guard for grinding also a sleep apnea treatment?
“A conventional grinding guard and a sleep-apnea appliance have different purposes. Do not assume that a guard protecting teeth will treat airway obstruction. If you have both concerns, tell us so the dental assessment and medical sleep plan can be considered together.”
Can an oral appliance change my bite?
“Oral appliances can cause discomfort or changes in how teeth meet, which is one reason follow-up matters. Report jaw symptoms, tooth discomfort or a persistent change in the bite. We can review the fit and coordinate any treatment adjustments with the sleep-care plan.”
Does mouth breathing always mean a dental problem?
“Mouth breathing can have different causes and should not be diagnosed from dental appearance alone. I consider the oral findings and symptoms, and may recommend assessment by an appropriate medical professional. The aim is to understand the cause before choosing exercises or an appliance.”
Restorative care & your first visit6 questions · Bring the information that helps shape the plan.
Does Dr. Sara also provide general dentistry?
Yes. Her R&H role includes general and restorative dentistry. Mention dental pain, damaged restorations or routine-care needs as well as any airway-related concerns.
What records should I bring?
Bring your medicines and medical history, previous dental records and any sleep study or appliance prescription. These help the clinicians understand which decisions have already been made.
How is the cost of an appliance decided?
Ask for a quote after assessment that distinguishes consultation, records, the device, fitting, adjustment and reviews. Reception can explain the current fee structure.
Can the first appointment answer everything?
It may identify the next steps, but some decisions need further records or medical input. Ask what remains to be established and who will coordinate it.
Should old fillings be replaced simply because they contain metal?
“An intact filling should not automatically be removed because it contains metal. Replacement also affects tooth structure. I assess its condition, any decay and your medical concerns before recommending a change, and explain the reasons if replacement is clinically appropriate.”
Can I request metal free dental treatment?
“You can discuss material preferences before treatment. I will explain suitable options and their limitations for the tooth involved. A preference is an important part of consent, but the plan still needs to protect dental health and account for any confirmed sensitivities or allergies.”
Follow-up & ongoing support7 questions · Keep the assessment connected to care.
Will a sleep appliance need follow-up?
Yes. Dental reviews and appropriate medical follow-up help assess comfort, dental effects and treatment effectiveness. Ask how those reviews will be organised before starting.
What if an appliance causes discomfort?
Contact the treating clinician for advice rather than adjusting it yourself. Explain the symptoms and when they occur so the team can recommend the appropriate review.
Can I bring an appliance made elsewhere?
Yes, bring the appliance and any instructions or records. The team can explain whether it can be assessed locally and whether the original clinician needs to be involved.
How do I book with Dr. Sara?
Use the R&H consultation link or call 952 81 44 44. Mention whether your main concern is general dentistry, snoring, diagnosed sleep apnea or myofunctional assessment.
How do we know whether an oral appliance is working?
“Feeling better is useful information, but it may not fully show whether sleep apnea is controlled. Follow-up with the sleep clinician, including testing when indicated, helps assess effectiveness. Dental reviews also check the appliance, teeth, gums and jaw comfort over time.”
Why do you ask about dry mouth?
“Dry mouth can affect comfort and make oral care more difficult. Medicines, health conditions and other factors may contribute. I ask about timing, symptoms and changes in your routine so we can discuss prevention and whether a medical or dental review is needed.”
What does prevention look like in biological dentistry?
“Prevention means practical care matched to the person: reviewing dental risks, discussing cleaning habits and choosing treatments when there is a clinical reason. Your preferences matter, but they should sit alongside evidence and regular reassessment rather than replace examination and diagnosis.”
