What are the risks of dental implants?
Dental implants have a 10-year success rate of 88–95%. Risks include infection, nerve damage, and implant failure — but serious complications are rare when placed by an experienced specialist. At DenCos, implantologist Dr. Gang Wu minimises risk through 3D planning and periodontal expertise.
How long does dental implant recovery take?
After dental implant placement, most patients experience mild discomfort for 3–5 days. Full osseointegration takes 3–6 months. Pain is comparable to a tooth extraction and manageable with standard medication. DenCos implantologist Dr. Gang Wu provides structured aftercare in Hoofddorp.
Do you need bone grafting for a dental implant?
Bone grafting rebuilds jawbone lost after tooth extraction, periodontitis, or trauma — creating a stable foundation for dental implants. Procedures include socket preservation, sinus lifting, and block grafts. At DenCos, periodontist-implantologist Dr. Gang Wu performs all bone augmentation procedures in Hoofddorp.
What does periodontal treatment involve?
Periodontal treatment ranges from scaling and root planing (deep cleaning) for early-stage gum disease to flap surgery for advanced periodontitis. Treatment stops bone loss and preserves teeth. At DenCos, periodontist Dr. Gang Wu provides the full spectrum of care in Hoofddorp.
What causes gum recession and how is it treated?
Gum recession occurs when gum tissue pulls back from the teeth, exposing the roots. Causes include aggressive brushing, periodontitis, and genetics. Treatment ranges from deep cleaning to gum grafting. DenCos periodontist Dr. Gang Wu treats all stages in Hoofddorp.
What is peri-implantitis and how is it treated?
Peri-implantitis is a bacterial infection that destroys bone around a dental implant — it is the leading cause of late implant failure. It affects 10–20% of implant patients. Prevention through regular maintenance is key. At DenCos, periodontist-implantologist Dr. Gang Wu detects and treats peri-implantitis early.
Does Invisalign cause bad breath?
Invisalign does not inherently cause bad breath. Halitosis during aligner treatment results from bacterial biofilm on uncleaned aligners and poor oral hygiene — both preventable. At DenCos, Dr. Jing Guo provides personalised hygiene protocols to keep breath fresh throughout treatment.
Does Invisalign cause tooth sensitivity?
Tooth sensitivity during Invisalign is caused by orthodontic force on teeth, not the aligner itself. It typically peaks on days 1–3 of a new aligner and subsides within a week. At DenCos, SmartTrack material and precise ClinCheck staging minimise discomfort.
What is an Invisalign Diamond Apex provider and why does it matter?
Invisalign Diamond Apex is the highest provider tier (top 1% in Europe by case volume). It guarantees up to 52% discount on aligners — passed on as competitive pricing — plus broader clinical experience and fewer refinements. DenCos in Hoofddorp holds Diamond Apex Status.
Does Invisalign hurt? What to expect during treatment
Invisalign causes mild pressure and temporary discomfort, not sharp pain. A randomised trial found fixed braces caused significantly more discomfort than aligners during the first week (P < 0.05). SmartTrack material reduces pain intensity and pressure upon insertion. At DenCos in Hoofddorp, specialist orthodontist Dr. Jing Guo (Diamond Apex, top 1% Europe) uses the latest Invisalign technology for maximum comfort.
How long does Invisalign take? Treatment timelines explained
Invisalign treatment typically takes 12–18 months for moderate cases, 6–9 months for mild crowding, and up to 24 months for complex malocclusions. At DenCos, Diamond Apex experience (3,000+ cases) means fewer refinements and shorter treatment times.
Can You Get Invisalign with a Missing Tooth?
Yes, Invisalign can treat most patients with missing teeth. At DenCos in Hoofddorp, orthodontist Dr. Guo and periodontist-implantologist Dr. Wu plan space closure or implant placement together under one roof.
Frequently asked questions about orthodontic treatment
Invisalign suits ~99% of cases at DenCos. Aligners change every 1–2 weeks, worn 20–22 hrs/day. Check-ups every 6–8 weeks. Cost €2,000–€4,500+. Under-18 partially insured. Specialist Dr. Jing Guo, Diamond Apex top 1% Europe.
What Is Periodontitis? Causes, Symptoms, and Treatment
Periodontitis is a chronic bacterial gum infection that destroys bone supporting your teeth. It affects over 50% of adults and is the leading cause of tooth loss. DenCos periodontist Dr. Gang Wu treats all stages in Hoofddorp.
Do you need a retainer after Invisalign?
Retainers are essential after Invisalign to prevent teeth from shifting back. Without retention, relapse is likely because periodontal fibres need up to 12 months to stabilise. At DenCos in Hoofddorp, specialist orthodontist Dr. Jing Guo plans retention from day one — combining fixed bonded retainers with Vivera clear retainers. Diamond Apex Status means up to 52% discount on Invisalign retainers.
What does the orthodontic treatment journey look like?
Orthodontic treatment at DenCos follows 6 phases: consultation and goals, diagnostic records, 3D planning, active treatment (12–24 months), interdisciplinary care if needed, and retention. Supervised by specialist Dr. Jing Guo in Hoofddorp. No referral required.
Does Invisalign cause gum recession? What the evidence says
Invisalign does not directly cause gum recession. Risk depends on gingival biotype, tooth movement direction, and oral hygiene — not the appliance type. At DenCos, periodontist Dr. Gang Wu monitors gum health throughout orthodontic treatment.
What Is a Dental Implant? Procedure, Types, and Candidacy
A dental implant is a titanium screw placed in the jawbone to replace a missing tooth root. After osseointegration (3–6 months), a crown is attached for a permanent, natural-looking result. At DenCos, implantologist Dr. Gang Wu places and restores implants in Hoofddorp.
Can Invisalign fix an overbite?
Invisalign can correct most dental overbites by intruding front teeth and extruding molars using clear aligners. A case-series study showed an average 4.1 mm overbite reduction. At DenCos in Hoofddorp, specialist orthodontist Dr. Jing Guo (Diamond Apex, top 1% Europe) treats deep bites with ClinCheck AI planning.
Types of Braces: Which Orthodontic Treatment Is Right for You?
Orthodontic options include metal braces, ceramic braces, lingual braces, and Invisalign clear aligners. At DenCos in Hoofddorp, 85% of patients are treated with Invisalign — with Diamond Apex top 1% expertise.
What happens at an Invisalign consultation?
An Invisalign consultation at DenCos is a focused 20–25-minute appointment where specialist orthodontist Dr. Jing Guo discusses your concerns, reviews your dental history, and identifies your treatment goals. Diagnostic records (photographs, X-rays, iTero 3D scan) are collected at a separate records appointment, followed by a ClinCheck 3D treatment plan review at a planning appointment.
How do you take care of your teeth after Invisalign?
Invisalign aftercare centres on retainer wear, oral hygiene, and scheduled check-ups. Wear your retainer full-time for the first 3–6 months, then nightly long-term. At DenCos, Diamond Apex Status means up to 52% discount on Vivera retainers.
Can Invisalign fix a crossbite?
Invisalign can correct most mild-to-moderate anterior and posterior crossbites using clear aligners with attachments and elastics. The AAO recommends early crossbite evaluation to prevent asymmetric jaw growth. At DenCos in Hoofddorp, specialist orthodontist Dr. Jing Guo (Diamond Apex, top 1% Europe) treats crossbites with ClinCheck AI planning and interdisciplinary support from periodontist Dr. Gang Wu.
How Much Does Invisalign Cost in the Netherlands?
Invisalign in the Netherlands costs €2,000–€4,500+ depending on case complexity. Under-18 treatment is partially insured. DenCos's Diamond Apex Status gives up to 52% discount on aligners — the highest in NL.
What is Invisalign? Everything you need to know
Invisalign uses clear removable aligners to straighten teeth without metal braces. Treatment takes 12–18 months, costs €2,000–€4,500+ in NL, and is partially insured for under-18s. At DenCos, Dr. Jing Guo is Diamond Apex top 1% Europe.
Can Invisalign change your face shape?
Invisalign can subtly improve facial balance by correcting bite issues that affect lip, jaw, and chin position. A study of 68 patients found clear aligners produced statistically significant improvements in lower-third facial aesthetics. Changes are dental, not surgical — Invisalign moves teeth within existing bone. At DenCos in Hoofddorp, specialist orthodontist Dr. Jing Guo (Diamond Apex, top 1% Europe) uses ClinCheck to preview facial changes before treatment.
How to fix an open bite: treatment options explained
An open bite is a malocclusion where the front teeth do not touch when biting down. Invisalign corrects most adult open bites via incisor extrusion and molar intrusion — a study of 50 patients showed improvement from −3.5 mm to +1.5 mm overbite (P < 0.001). At DenCos in Hoofddorp, specialist orthodontist Dr. Jing Guo (Diamond Apex, top 1% Europe) treats open bites with ClinCheck AI planning.
Orthodontist or dentist for orthodontics: why specialist care matters
In the Netherlands, only a registered orthodontist has completed a 6-year dental degree plus a 3–4 year full-time university specialisation. At DenCos in Hoofddorp, specialist Dr. Jing Guo (BIG 19918762902) and periodontist Dr. Gang Wu work under one roof for complex cases.
